Connecting a touch light switch from China. Livolo connection diagrams
Quite often, it is necessary to change conventional electrical appliance switches for new ones due to their rapid wear. They were replaced by more reliable touch switches (CB). The principle of their work is as simple as possible. Devices can be made by hand. The photo below shows a switch with a sensor located on top and an indicator LED on the bottom.
The appearance of the touch switch
A light touch on the sensitive element is enough to turn on the light. Touch switches are commonly used to control lights, electric curtain rods and other low power devices.
Benefits of CB
- Convenience compared to a key switch, which does not always switch immediately. The devices are completely silent and there is no need to make an effort to turn them on.
- You can choose stylish models that will decorate the premises.
- The galvanic isolation of the circuit makes the device completely safe. The sensor can be touched with wet hands, the switch is sealed.
- The absence of mechanisms that can break. The whole circuit consists of electronic elements.
- The ability to combine with remote control of light, as well as the creation of several switching channels in one device.
- The possibility of making your own hands.
Operating principle
Any Sensor switch functionally divided into three parts:
- a sensitive element (sensor) that reacts to the touch or proximity of fingers;
- a semiconductor circuit that amplifies a weak electrical signal from the sensor;
- a switch (relay or thyristor) that turns the load on and off.
The figure shows a touch switch circuit with a supply voltage of up to 16 V. It is a simple semiconductor cascade amplifier. Used for small loads. There is enough static electricity in the human body to open the first transistor of the cascade if you touch a bare conductor connected to the base with your finger.
Diagram of a simple touch switch from a three-stage amplifier
An LED is connected as a load at the output of the third stage, which serves to demonstrate the operation of the circuit. Instead, a relay is installed in the switch, for which a more powerful transistor can be selected. The sensor can be copper foil.
When you touch the sensor, the first stage opens, then the signal is amplified on the next two and the output becomes 6 V. It is enough to trigger the relay, which turns on the lamp with its contact (not shown in the diagram).
Scheme
The figure shows a diagram of a two-stage touch switch, which you can do yourself.
Switch circuit with two transistors
When touching the sensor E1, the voltage from the human body is supplied to the amplifier through the capacitor C1. Relay K1 is connected as a load, which is triggered at the next touch, turning on or off its power contacts for supplying the lamp. The diode VD1 is designed to protect the transistor VT2 from voltage drops, and the capacitor C2 smoothes out the ripple.
The relay is selected for a trip current of 15-20 mA (type RES55A or RES55B). You may need to change the value of the resistor R1 in order for the relay to work reliably. First, a 50 ohm variable resistor is connected instead of it and adjusted until the relay from the sensor works. Then the resistance value is measured and a constant resistor with the appropriate rating is found.
Foil textolite, copper plate or metal with anti-corrosion coating is used as a sensor. It is easy to make with your own hands. If the sensor is installed at a distance from the board, the lead wire must be shielded.
The voltage source is a 9 V battery or a do-it-yourself power supply from the mains. A charger might work.
It is better to assemble the switch circuit on the board, but you can also solder it with wires, since there are few parts. To connect them to each other, wires 2-3 cm long are used. To connect the sensor and relay contacts, the length of the conductors will be no more than 10 cm.
When soldering, it is important not to overheat the transistors and the 0.22 microfarad capacitor.
Transformerless power supply from a 220 V variable network does not require a separate source. The device on the triac is quite sensitive and works reliably. In the diagram below, there is no galvanic isolation from the lighting network, but the sensor protection against high voltage are resistors R1 and R2 with a total resistance of 12 mΩ, as well as a field-effect transistor VT1 with a large resistance of the drain-source-gate transition. The sensitivity of the circuit is selected by changing the resistance R2.
In such circuits, when they are energized, only the E1 sensor is allowed to be touched.
Scheme of a touch electronic switch on a triac
The trigger is built on integrated circuit K561TM2 (DD1). From its output 1, the signal goes to the base of the transistor current amplifier VT2, the emitter of which is connected to the control output of the triac VS1. As soon as a voltage of 3 V appears on it, the triac opens and turns on the light source. The next time you touch the sensor, the trigger changes state and the opposite signal appears at output 1, turning off the EL1 lamp.
The load power for this circuit is not more than 60 V. If it needs to be increased, the triac is installed on the radiator.
There are circuits with dimming function. When briefly touching the sensor, the lamp will light up and go out. If you keep your hand on the sensing element, the brightness will increase and then decrease. Such a device is convenient to use for a table lamp at your desk. You can adjust the specific illumination by removing your hand from the switch. The figure shows a diagram of the touch controller.
Touch dimmer circuit
The signal is fed from the sensing element to the K145AP2 chip, and it controls the VS1 triac through the VT1 transistor. Power is supplied from the mains 220 V. LED HL1 is a voltage indicator and illuminates the sensor in the dark.
The household lighting switch has been constantly upgraded over the years of its existence. A new stage in the production of switches was the use of touch control technologies. Anyone who has ever used a mobile phone, tablet or payment terminal is familiar with the feeling of convenience of working with a touch panel.
However, for us ordinary users, control the lighting in their apartments and houses, using touch panel is new. And I think it will be interesting for many to get acquainted with how such a switch works and how this miracle of technology works in more detail.
Unlike conventional push-button switches, these switches are equipped with touch and remote control. The control is very simple and works on the principle of a sensor on mobile phone or tablet: touch the panel with your finger, the light turns on, touch again - it goes out. True, the sensitivity zone of the sensor is limited and you need to touch it in a specially designated place.
Except beautiful design and elegant appearance, I also liked the radio control function. When ordering switches, you need to keep in mind that the remote control may not be included in the kit and will have to be purchased separately. The radio remote control makes it possible to control the switch within a radius of 30 m.
Touch switch device
To be honest, until recently, I did not even suspect the existence of such interesting lighting control devices. It all started with a part-time job at one facility, it was necessary to complete repairs in a two-room apartment and install new sockets and switches to replace outdated ones. But the customer was not satisfied with the usual wiring accessories. He wanted something unusual, fresh and in the style of "Hi-tech".
When I was digging on the Internet and looking for exclusive options, I came across Livolo companies. It was a great alternative to a push-button switch (as the customer put it, "a white toggle switch with a button"). Having agreed with the customer, we decided that he likes this option the most and suits the interior of the room very well. After approval, I ordered the following products: 1) one-key touch light switch VL-C701R, 2) two-key touch light switch VL-C702R and 3) remote control for them VL-RMT-02.
I ordered switches and a control panel for them on trading platform Aliexpress. Their cost at the time of the order (December 2016), including delivery, was: single-key - 1372 rubles, two-key - 1670, control panel - 338 rubles. The parcel from China was 24 days.
To begin with, let's unpack the boxes with switches and see in what form they were delivered. Everything came in one common package, since the order was made from one seller. The packaging was a little wrinkled, but all the insides were intact.
Switches VL-C701R and VL-C702R Each is supplied in its own packaging. The tempered glass touch panel is packed in a box separate from the switch. That is, there were four packages in total: two switches and two panels for them. The set also comes remote control lighting VL-RMT-02. I would also like to note that the manufacturer offers a wide range of colors for touch panels that will suit any apartment design. I liked the gray color better, and I ordered a glass panel in this color.
Switches from Livolo are assembled very high quality and meet all European standards for electrical products. The body of the switch is made of heat-resistant plastics, and the tempered glass panel can withstand temperatures up to 300 C. Terminals for connecting wires are made of brass.
The front panel is a sensor that transmits signals to turn off or turn on the lighting to the control module. Touch panel attached to the switch with latches. To install the panel in its place, we present it to the case and gently press it until a characteristic sound is heard.
All touch light switches are pleasing to the eye LED backlight, which changes its color depending on the state of the switch. When the switch is off, the backlight glows blue, and when the switch is on, it glows red.
To turn it on or off, just touch the sensor in the selected area (circled circle) with your finger. The lighting circuit is switched by an electromagnetic relay, so a slight click can be heard when the switch status changes.
The touch switch is equipped with open circuit protection. When might a regime arise? The most commonplace is the burnout of the llama or the shutdown of the circuit breaker in the shield, or the loss of voltage electrical network. When such a situation occurs, the circuit breaker automatically switches to the "off" mode and remains in it even when the power supply is restored. After the fault has been eliminated, the circuit breaker can be turned on normally by touching the panel or using the control panel.
These models of switches have a built-in radio module for remote control. Management is carried out by a single press of the button on the control panel. The control panel allows you to control the switch at a distance of up to 30 meters from any room in the house (not necessarily in the line of sight of the device). The remote control is powered by a 12 volt battery, which is not included in the price.
Specifications of livolo touch switch
Nowadays, touch control is present in almost all household appliances. Everyday use this technology, led to the introduction of such a function in light switches. The front panel of the device is made of optical glass OptiWite has an unusual design, which allows it to find its place in any interior solution.
By their own technical specifications, touch light switch VL-C701R and VL-C702R in no way inferior to the classic push-button switch.

- 9. Degree of protection of the case: IP20.
What types of lamps can be switched with a touch light switch? Dear friends, as you know, today the problem of blinking LED and energy saving lamps. Blame the backlight, which is used in light switches. I have repeatedly written about this in my articles, if you are not already in the know, then you can read one of them the reason for the blinking of the LED lamp in the off state. It describes not only the cause, but also a way to solve it.
The livolo company assures that it is allowed to use any type of lamps with touch switches of their company, ranging from conventional lamps incandescent and ending with the familiar to everyone LED lamps and ribbons. But there is a fly in the ointment in this barrel of honey.
The only drawback of the VL-C701R(VL-C702R) is the backlighting (or blinking) of low power LED and fluorescent lamps (up to 15 W) when the switch is off. That is, if a lamp (s) is connected to the switch total power less than 15 W, then the lamp may flash in the off state.
As a solution to this problem, Livolo proposes to use special LED adapters. I didn't buy this adapter. We will check this already in the video review - see soon on the YouTube channel.
A little about labeling
How did you notice Dear friends, in the text of this article there are designation markings such as VL-C701R and VL-C702R . All these numbers and letters carry some information, let's try to decipher the Chinese logic.
The marking of each touch switch begins with the letters "VL" - this is a well-encrypted name of the manufacturer's company - " Livolo". Immediately after the hyphen comes the encoding "W, R, C6, C7, C8" - this is the designation of the device series. The numbers following the series in the code (01, 02, 03 ...) are the designation of the number of switched lines (that is, a one-, two-, three-gang switch). At the end of the list is a Latin letter (there may be several). R - possibility of radio control; S - through switch; D - dimmable sensor; T - switch with built-in timer (turns off after 30 seconds).
Setting up the remote control
Touch switches look really very stylish - they will look great in the hall, and in the corridor, and in the kitchen, and anywhere else. And such devices are good because they can be controlled remotely. To do this, you just need to order a universal remote control over the Internet. Price this device, which is a keychain with a carabiner and a metal front panel, is not so great.
There are four buttons on the remote control panel, they are designated in Latin letters - A, B, C, D. This device works on a 27A battery with a voltage of 12 volts. Such a remote control is compatible with a variety of touch switches, in particular, with popular switches brand LIVOLO series C6 and C7.
Setting up this remote control is easy. First of all, you need to press the button of the touch switch (at the same time, it should be in the “off” position) and hold it until the sound signal “Pi” is heard from the touch device - in time it is about 5 seconds.
Then you should press one of the buttons on the remote control (A, B or C), as a result of which another beep should sound - it means that the “binding” procedure is completed. Now the button that we pressed on the remote during binding can be controlled (disabled, enabled) by touch switches from a distance. All other buttons on the switches are tied to the remote control in exactly the same way.
It is worth noting that several touch devices can be tied to one button of the remote control. That is, several buttons and even several remotes can be tied to one sensor. There is information on the Internet that you can make 8 such bindings (I haven’t tried it myself).
Detaching the sensor from the remote control is also very simple. To do this, touch the sensor and hold it for about ten seconds. After five seconds, the first beep will sound, but this should not be taken into account. And only when one more, second sound signal is heard - all previous settings will be reset.
Operating range of the universal control panel VL-RMT-02 is 30 meters. This is quite enough for everyday use - the remote control will properly perform its functions throughout the entire territory of an ordinary apartment.
Connecting a single-key touch switch Livolo VL-C701R
So, let's figure out how to connect a 220 Volt touch light switch. In fact, it is no different from the connection diagram of a single-gang switch.
There are two terminals on the switch body marked as "L-in" and "L-load". Terminal "L-in", the literal abbreviation of which sounds like - "live line terminal". If you use electrical translation, it means something like this: “live line” - live line, “terminal” - contact, contact screw. In general, this is a contact for connecting a PHASE wire (the one that came from the junction box).
The “L-load” terminal in the instruction manual is called “lightin terminal”, it translates something like this: “lightin” - lighting devices, “load” - load. That is, this is a contact for connecting a wire that goes to a lighting load (a wire that goes to a lamp or chandelier).
As you can see, there is nothing complicated in this “electronic miracle”, everything is like in a conventional switch, there are two terminals “phase-input”, “phase-output”. We strip the wires to the desired length and connect to the terminals.
If you install touch switch instead of the old one, just unscrew the wires from the old one and connect it to the new one. The main thing is to decide where the phase is and connect it to the desired contact of the touch light switch (“L-in” contact).
The only thing I would advise, if you use a cable with a stranded core, use NShVI lugs. The touch switch has screw-type terminals, and if you push a bare stranded core there when tightening, you can easily crush it.
And this is what the Livolo switch looks like from the side
How to connect a two-key touch light switch Livolo VL-C702R
The VL-C702R switch is designed to switch two independent lighting lines (as evidenced by coding 02), simply speaking, a two-button switch. And there is no difference between its circuit and the connection diagram of a two-gang switch.
On the back of the sensor, you can see not two, but three terminals for connecting wires: "L-in", "L1-load" and "L2-load". The terminals "L1-load" and "L2-load" are connected to wires going to a group of fixtures (each to its own group).
We fix the mechanism in the socket
Regarding the installation of the sensor. Installing a touch light switch carried out in a conventional socket. There are no spacer tabs for fixing on it, so the switch support is attached to the socket with screws. By the way, the screws are included with each sensor.
Touch switches are, of course, a new word in household lighting control technologies. Their convenience and comfort are obvious, and their cost is gradually decreasing. All this suggests that soon sensory devices and remotes for them can massively replace the usual push-button switches.
Technologies do not stand still, and now we already have a touch switch in widespread use, which allows us to bring the lighting control system in the house to a fundamentally new level.
Why you need such a device, what it is and how it works, our article will tell. Thanks to this, you can make a do-it-yourself touch switch for 12 or 220 volts without any problems, and the connection itself, like homemade device, and the purchase will not be difficult.
How the device works
The touch switch looks like a standard touch panel and looks like a plate consisting of crystal glass with printed markings. Such a dimmer can have the most diverse appearance. The switch circuit is a semiconductor device. It provides control of the energy consumer.
The touch dimmer can be connected to fixtures to control the light level. It can be any lamp. But besides this, you can connect electric cornices and other modern electronic devices included in the "smart home" system.
The device circuit (at 220 or 12 volts), regardless of the number of lamps connected to it, consists of three main functional parts:
- decorative profile or front plate. It contains a sensitive element. The profile has the ability to respond to touch or approach;
- semiconductor circuit. Such a circuit is the "soul" of the switch. The circuit is responsible for the analysis, control of fixtures and turning on the light. It converts the sensitive signal that the decorative profile perceives into an electrical impulse;
- switching part. The dimmer in this part perceives the converted electrical signal. She is responsible for various activities with an electric circuit: smooth adjustment of the light of fixtures, opening, closing.
Dimmer device
The principle of operation of the device is based on the following: when the front part is touched, a signal occurs, which is further converted into an electrical impulse and activates the switching part of the device.
What is a good device
Touch off is a modern technological solution for comfortable and efficient control of the work of lamps in the house. When you install it, you get the following benefits:
- the life of the light source, regardless of the type of lamp, is significantly increased due to the smooth switching on of lighting;
- great quality;
- high reliability;
- compatibility with any light sources;
Note! The touch dimmer can be connected to any type of light source: diode lamps, induction lamps, incandescent lamps, etc.
Switch with motion sensor
- there are models with a voltage of 12 and 220 volts;
- the presence of an economical mode of operation, as well as the ability to adjust power;
- the possibility of embedding in a standard lighting scheme or a smart home system.
In addition, the touch switch today is often equipped with additional functionality. These additional options include:
- the ability to use a dimmer with a remote control. With it, you can remotely control the work of lamps in the house. Several switches of the same type can be connected to the console;
- equipping switches with temperature, motion, light sensors, etc.
Note! The most common addition is a motion sensor.
As you can see, using such a switch (for example, 12 volts), you can greatly simplify your life in your own home.
Selection rules
To take full advantage of all the benefits, you need to choose the right sensor model of the switch. When choosing, you need to be guided by the following criteria:
- the number of lamps to be connected;
- location of the dimmer;
- is it planned additional connection electrical appliances;
- operating voltage (12 or 220 volts);
- the need for additional features.
Only when these parameters are taken into account will you be able to make the right choice.
And now consider the most popular models.
Basalte
These are products of the Belgian company Basalte. The company provides a huge selection of a wide variety of models of touch switches.
Switch Basalte
Such devices are always High Quality but they are also very expensive.
Livolo
Livolo touch switches are domestic products. Therefore, their price will be several times less than that of foreign firms.
Switch Livolo
At the same time, Livolo touch switches, with their affordable price, may be slightly inferior in quality. In rare cases, incorrect operation of the device is possible if fluorescent or LED lamps are connected to it.
Legrand
The switches of the French company Legrand are of excellent quality and functionality.

But here again we have to face high cost imported products.
By functionality and the variety of models presented, in the market of our country, all three brands have almost the same distribution. They differ only in price and, a little, quality.
How to install
Wiring diagram
Connection sensory models switches are as follows:
Note! The installation of the device is generally similar to the installation of a standard pushbutton switch;
- turn off the electricity;
- dismantle the old switch;
- filming upper part dimmer
- we connect the wires "phase" and "zero" according to the scheme to the corresponding terminals;
- install the dimmer in the mounting box and fix it here with screws and spacers.
As you can see, choosing and installing a touch switch is easy. With such work without due experience it is possible to cope in ten minutes. As a result, you will modernize your own home, adding a few items to home comfort and coziness.
Details about the switch with motion sensor
Choosing a street motion sensor to turn on the light
Hi all!
The idea stuck in my head to install touch-sensitive light switches in the apartment. I put off this idea for a long time, but finally decided and purchased one such device.
I want to tell about him.
The thing is new to me, I have not seen any of my friends and have not personally used it. Inspired by the reviews and reviews of people from the Internet. It was decided to purchase one copy for, so to speak, a sample. The location of one of the switches (I was going to replace it) in my apartment defies any logic and convenient use has nothing in common. Therefore, the ability to control the new switch from the remote control was a big plus for me.
And here is the package with the device on my desk. 
Inside is a small box with a designation of the switch configuration. From the information about the manufacturer, only the inscription Made in China. 
The contents of the box are fully consistent with the list on the site. It includes: the switch itself, a remote control, an element connected to electrical circuit(optional) and instruction sheet in English and Chinese. 
Specifications:
Rated voltage: AC 110-240
Max load: 3-300W, 800W total
Operating Temperature: -20°C ~ 70°C
Relative humidity: 10% ~ 93% (non-condensing)
Working frequency: 50/60Hz
Power Consumption: 0.02W
Number of inclusions: 100,000 times
This switch works with one consumer, there are also versions for working with two and three. (I mean connection lines).
The appearance is as I expected, considering the photo on the store's website. The workmanship is quite decent, everything is also assembled evenly and neatly. 
The main dimensions of the device (in mm).
After a cursory glance at the instructions, he proceeded to dismantle the old switch. But everything turned out to be not so simple. The recess in the wall turned out to be gouged and the mounting box also required replacement. As a result, collected, so far, everything is as it was. And in order to satisfy my interest, I connected the switch to table lamp. There were no difficulties here. The switch works from the slightest touch in the area where the control LED is lit, the switching occurs completely silently. I noticed that the sensitivity of the sensor is enough to trigger when the finger is at a distance of about 3-4 mm from the switch. By the way, the brightness of the LED (which shines in the off state) is just enough to see the location of the switch in the dark. 
Disassembly
We remove the decorative cover, which is a Plexiglas plate glued to a plastic frame. 
The white area is the sensitive element that responds to touch. Next, remove the top board with the sensor. It is connected to the bottom through the "block" of contacts. 
Individual photos. 
The bottom board is attached to the base of the switch with three self-tapping screws. Unscrew and take out. 
Back view. 
I'm not good at electronics, so detailed description I can't give. As I understand it, the aluminum plate is designed to remove heat and is screwed to the element that is responsible for switching. I can’t measure the temperature of the plate and other elements, but tactilely for 2 hours of operation with a load of a 60W incandescent lamp, nothing has heated up.
Here is what is under the plate itself. 
Remote control.
The switch is equipped with a remote control operating at a frequency of 433 MHz. Remote control design in the form of a moped alarm keychain. 
Assembled quite well. The remote control has four programmable buttons, which, to avoid accidental pressing, are closed with a curtain, although they are still tight enough to accidentally press. When pressed, the blue LED lights up. Most devices of this type are equipped with such remotes (as I understand it, in order to reduce their cost), and for some you generally need to buy separately. It is possible to purchase a more "home" remote control.
Having unscrewed 3 self-tapping screws, the remote control is decomposed into 3 parts, the chrome insert is made of metal. 
Power comes from a 27A battery. 
.
Pleasantly surprised by the range of the remote control. In the apartment, he worked from anywhere, which is sufficient for me. I decided to go outside to test the range (I live on the second floor), moving away from the house I continued to turn on and off, at a distance of about 50 m everything works (then the window disappeared from the view around the corner). I think this range will find application in the private sector.
Learning the buttons on the remote control is quite simple. The buttons can be configured to three modes of operation:
1. Turn on-off,
2. Only turn on,
3. Just turn off.
To adjust the initial position of the switch - off. We touch the sensor and wait for a single sound signal, then press the desired button on the remote control, hear the control beep and you're done - the button is set to the first mode of operation. For clarity, I made a video in which you can see the settings of the buttons for different modes.
I note that I used the switch only with an incandescent lamp and there are no problems when working with it. I read that when connecting some housekeepers, false positives sometimes occur. To do this, the manufacturer completes the switch with such an element (interference suppression capacitor)
which is connected to the circuit according to the instructions
and is designed to eliminate the problem of false positives.
In general, I liked the switch, now I plan to buy another one of the same only for 2 lines, and perhaps some more aesthetic remote control.
That's all. Thanks to all. I hope the review is useful to someone. I plan to buy +27 Add to favorites Liked the review +23 +50
Hello, dear readers and guests of the Electrician's Notes website.
About a year ago, I told you about, which I first installed on one of my objects.
The switch showed itself on the positive side and for all this time of operation there were no complaints about it.
In addition, due to its glass panel and backlit sensor, it has a rather pleasant appearance.
In this regard, it was decided to install exactly the same switches throughout the apartment.
This article will focus exclusively on the corridor.
In the corridor, it is necessary to install walk-through switches to control the lighting from two places - in the hallway and at the end of the corridor in front of the entrance to the rooms.
Now you will not surprise anyone with this - this is a common practice. And it's really very convenient, especially in my case the corridor is long enough and, for example, to turn the lighting on or off, you need to return to the hallway every time. Or walking through the entire corridor in complete darkness, stumbling and leaning against the walls, is also not entirely comfortable. Another thing, turned on the light, went through the corridor and turned off the light. Nice business!
As you can see, both in the hallway and at the end of the corridor,. In the first socket in the hallway, a conventional Livolo touch switch will be installed to control the lighting of the hallway (2 lamps), and in the second socket - a Livolo walk-through switch for the corridor (9 lamps). Similarly, at the end of the corridor, in the first socket there will be a conventional touch switch to control the lighting of the room, and in the second socket there will be a pass-through switch.
In addition to the VL-C701R touch switches, two VL-C701S single-line switches from Livolo were ordered.
Two doubles were also ordered. glass frames(panels) VL-C7-C1 / C1-11 white (White).
If you need a similar glass panel, only black (Black), then the code will be VL-C7-C1 / C1-12. The last digit at the end of the cipher determines the color of the panel.
Here is an example of how the VL-C7-C1 / C2-12 panel looks.
In addition to white and black, panels can also be ordered in other colors, such as gold (13) or gray (15). In general, I think it will not be difficult to choose a glass panel for the design of your room.
In the case of a single-line pass-through switch VL-C701S has one sensor, i.e. it can control only one load (in my case, one group consisting of 9 lamps).
For information! In addition to the VL-C701S single-line feed-through switches, there are also VL-C702S two-line feed-through switches on sale, which have two sensors in the housing, and, accordingly, they can control two groups of lamps.
By appearance VL-C701S pass-through switches are exactly the same as conventional VL-C701R touch switches, which I already told you about in detail (link at the very beginning of the article), so I won’t dwell on this now, but I’ll go straight to their connection diagram.
Connection of Livolo walk-through switches
The fact is that there is practically no information on the Internet on the connection diagram of Livolo feed-through switches, or rather, there is, but the same diagram appears everywhere, which is also included with the switches.
As you can see, the phase (red wire) is connected to the L (In) terminal of both feed-through switches, a jumper (blue wire) is made between the COM terminals of both switches, and the switching phase to the load (lamp) is connected to the L1 (Load) terminal of one of the switches. nearby switches.
This scheme is quite clear to me, but home craftsmen or novice electricians may have questions.
In this regard, I will publish my more detailed diagram, and at the same time I will show you, using a good example, the connection, setting up synchronization (pairing) and the principle of operation of Livolo feed-through switches.
So let's go.
As you can see, the Livolo single-line feed-through switch has 3 outputs:
- L(In)
- L1 (Load)
For convenience of perception of the scheme, we denote the numbers of the switches: in the hallway, the switch No. 1, and at the end of the corridor - the switch No. 2.
Let me remind you that in this apartment all electrical wiring is made without junction boxes. Go and read in my separate article about the advantages and disadvantages this method electrical installation.
Let's start with the hallway.
There are 3 cables in the hallway socket box:
- power cable from the apartment panel VVGng (3x1.5)
- cable to hallway lamps VVGng (3x1.5)
Attention! Initially, I did not quite correctly put the cables into the sockets, because. in the upper socket there should be a hallway lighting switch, and in the lower socket there should be a pass-through switch No. 1 for corridor lighting. Therefore, part of the lived, for ease of connection, I immediately reset from the lower socket to the upper one, and vice versa.
First of all, we connect the zeros (blue) of all three cables with the help and carefully lay it deep into the socket.
Then we connect the phase (white) of the supply cable to the Vago terminal and here we also connect the phase (white) of the cable laid to the feed-through switch No. 2.
Why did I connect the supply phase through the terminal?! Yes, because the clamps of Livolo switches are designed to connect only one conductor, which is why I had to use an additional terminal.
From the phase terminal, we make a jumper to the lower socket to connect it to the L (In) terminal of the feed-through switch No. 1.
The remaining conductor (yellow-green) in the lower socket box is used as a connecting COM conductor between the feed-through switches. We, accordingly, connect it to the COM terminal of the feed-through switch No. 1.
Using the Vago terminal, we connect the PE conductors of the supply cable and the cable laid to the hallway lamps, and from the phase terminal we make a jumper to connect the hallway lighting sensor switch.
Carefully put all the terminals into the socket and connect the touch switch.
We connect the phase to the L (In) terminal, and the switching phase of the cable going to the hallway lamps to the L1 (Load) terminal.
Livolo switches are mounted in the socket exclusively on mounting screws (included in the kit) and they do not have any bursting legs.
The base of the switches is made of metal and allows you to use during installation.
And now we take the glass panel and snap it onto both switches at once.
From the side of the hallway, everything is ready.
Let's move on to the second place to control the lighting of the corridor.
As I already showed you, there are also two sockets installed here. On the left is the socket for the touch switch of the next room (do not pay attention to it, because it is connected from a separate line), and on the right is the socket for the passage switch No. 2.
In the socket box we are interested in, there are 2 cables:
- cable from feed-through switch No. 1 to feed-through switch No. 2 VVGng (3x1.5)
- cable to corridor lamps VVGng (3x1.5)
We connect the zeros (blue) of both cables using the Vago terminal, and connect the remaining cores as follows:
- phase from the cable from the feed-through switch No. 1 - to the L (In) terminal
- yellow-green core from the cable from the feed-through switch No. 1 - to the COM terminal
- switching phase from the cable of the corridor luminaires - to the L1 (Load) terminal
- the yellow-green core from the cable of the corridor lamps remains unused
For clarity, I am attaching the resulting connection diagram of the pass-through switches for lighting control from two places. It may sound complicated in words, but in fact everything looks quite simple.
The switch is installed in the same way, so I will not repeat this.
After installing the Livolo walk-through switches, they must be synchronized to work with each other. To do this, it is necessary to press and hold the sensor on the passage of switches No. 1 for about 5-7 seconds until a beep is heard. Then, on the passage switch No. 2, it is necessary to press and hold the sensor until it flashes 2 times. That, in principle, is the whole synchronization.
To reset the synchronization, you must press and hold the sensor for about 10 seconds until a double signal.
Lighting control from two places with Livolo switches
When you press the sensor (circle on the glass panel) of the passage switch No. 1, the corridor lighting is turned on. When you press the sensor again, the corridor lighting is turned off. This is, so to speak, controlling the lighting of the corridor from one place. But after all, we didn’t use pass-through switches in vain ?!
Of course, now the corridor lighting can be controlled from two places. For example, you can turn on the corridor lighting using the passage switch No. 1 in the hallway, and turn it off using the passage switch No. 2 at the end of the corridor, and vice versa.
By the way, I noticed such a feature that when lighting is controlled from the passage switch No. 1, the built-in relay on the passage switch No. 2 always works (clicks), which turns on the corridor lighting. Thus, it switches the load of the relay only through the passage switch No. 2. Here is such a small feature of the Livolo walk-through switches.
For more information about the operation of pass-through switches, you can see in my video:
P.S. On this, perhaps, everything. If you have any questions, then ask them in the comments below the article. And in conclusion, I will add that the range of Livolo does not end there. The site presents a large selection of switches, sockets, dimmers, timers, relays and other devices with different functionality and interesting design.Thank you all for your attention, see you soon.
