Connecting Legrand switches - diagram

Wiring accessories are used by consumers as functional devices and play an important role in interior design. Therefore, manufacturers, developing such devices, pay attention not only to the technical characteristics, but also to the appearance of the products, trying to ensure that the products meet the requirements of modern design. Among the world's manufacturers of electrical accessories, one of the first places is occupied by the Legrand company, whose products are distinguished by a variety of shapes and colors.

Legrand Company

Legrand Etika 3-key switch

The international company Legrand, headquartered in Limoges (France), was founded in 1866 and was originally engaged in the manufacture of table china. However, the company subsequently switched to the production of porcelain insulators (1904), and then focused on the production of electrical accessories (1949). Since then, continuously developing, the small enterprise has turned into a large international company with branches located in more than 60 countries around the world. A wide range of electrical products is manufactured at its enterprises, from sockets to the creation of complex technical solutions for electrical and information networks.

Legrand is the only company that offers Russian enterprises and trade organizations a full range of electrical equipment, developed taking into account the latest scientific and technical achievements and meeting the requirements of international standards.

Legrand products are fully certified for compliance with the regulatory and technical documentation in force in Russia.

Popular series and classification

Legrand Valena Life

Legrand offers consumers a wide variety of switches. All of them are divided into series, which differ from each other both in functionality and appearance. The most popular among them are the series:

  • Valena and Valena Life are one- and two-button switches and switches of a classic (square) shape, made in the colors "aluminum", "white", "ivory". Some models are equipped with backlighting.Valena Life products are distinguished by a gracefully curved shape of the keys, which allows you to turn on the light with a light touch of your finger.
  • Galea Life - waterproof models included in this series of one- and two-key products are distinguished by a strict design and original colors (dark bronze, titanium, mother-of-pearl, etc.). Many of them are backlit or display.

    Legrand celiane
  • GeaLine is a series of exquisite models with an extended range (premium class). They are produced in the colors "white graphite", "ivory", "titanium" and are characterized by an original combination of square frames and rounded keys. Attention is also drawn to the fact that genuine leather, porcelain, wood and glass are used for decoration.
  • Quteo is a series of one- and two-button switches and switches designed for outdoor installation on a wall surface (surface-mounted). Impact-resistant ABS plastic is used for the manufacture of their cases.
  • Plexo is a series of water-resistant one- and two-button models of the surface-mounted type. They are mounted in utility rooms (garage, basement, etc.) with high humidity (protection class IP55 or IP66).

    Legrand Plexo
  • Cariva is a series of low-cost one- and two-key models designed for office and residential installations. Some of them are backlit. Waterproof versions are also available.
  • Etika is a series of economy switches, the exterior details of which are made of plastic. Available in one- or two-key design. Their distinctive feature is the absence of a terminal block - the wires are fixed with a special nut.

All Legrand switches and switches are classified by function, type of installation and method of control.

Legrand switches

By functional purpose, the following product groups are distinguished:

  • Switches are devices equipped with one or more pairs of contacts. In the on state, these contacts are closed (the lighting is activated), and in the off state, they are open (the lighting is off). As a rule, the switches open only the contacts to which the phase wires are connected, however, there are also two-pole versions - in them, the contacts also break the neutral ("zero") wire.
  • Switches are devices that use three or more contacts. In the “On” position, the first and second contacts are closed, and in the “Off” position, the first and third. Switches with three contacts are sometimes called bi-directional switches. They are used, as a rule, in cases where the lighting is controlled from two places.
  • Cross switches are devices that switch two separate lines in a cross (when switching the phase and "zero" are reversed). Such switches are also called "intermediate" - in lighting control schemes they are installed between switches in two directions, which allows you to turn on light sources from three or more places.
  • Circuit breakers are devices designed to protect light sources from overvoltage or short circuit.
Legrand series for surface-mounted installation

By type of installation, switches / switches are divided into surface-mounted and built-in ones.

  • Overheads are used with an open type of wiring.
  • Built-in ones are intended for use with hidden electrical wiring. Unlike the overhead models, their actuator is hidden in a specially made recess on the wall surface.

By the way of control, switches / switches are:

  • push-button;
  • sensory;
  • keyboards;
  • responsive to the movement of people.

Push-button type switches / switches are the most common. Most residential and office premises are equipped with them. Between themselves, such devices differ in the number of keys with which you can control certain groups of lighting fixtures.

Legrand Celiane Touch

The introduction of innovative technologies allowed the developers of Legrand to create executive mechanisms:

  • operated by a light touch of the hand (touch-type models);
  • activating lighting when it appears and turning it off when there are no people in the room (devices equipped with infrared sensors).

Models with push-button control, which have appeared relatively recently, are easy to use and are able to bring a certain originality and elegance to the interior of the room. Moreover, their use will require some time from the user to get used to.

Connecting Legrand switches / switches

Installation of Legrand switches / switches is carried out in accordance with the attached instructions. In addition, the connection diagram is duplicated on the back of the product.

How to connect a Legrand switch

One-button switch wiring diagram

For a properly connected Legrand switch (two-key or one-key), the keys in the on state occupy the "up" position, and in the off state - the "down" position. For this, the phase wires are connected to the input terminals, which are marked with the letter L or arrows indicating the path to the center of the breaker. In this case, the conductors going to the load (lighting lamps) are connected to the output terminals, indicated by arrows indicating the direction from the center of the switch.

This ensures that the circuit breaker is connected to the luminaires according to the "phase -> circuit breaker -> load -> zero" scheme, which ensures that the load is not energized after switching off.

If you connect the phase wire to the output terminals, and the wires going to the load - to the switch input, the key will be in an inverted position and there will be a risk of electric shock to the user when replacing the light bulb, which will be energized after switching off.

All work with an electrician must be carried out in a de-energized room.

Connect the switch in the following order:

  1. De-energize the power grid.
  2. Using a flat screwdriver, carefully remove the keys and frame from the switch.
  3. Strip the electrical wires to the length indicated on the back of the switch.
  4. Connect the electrical wires to the appropriate terminals of the switch.
  5. Install the switch in the back box.
  6. Replace the frame and keys.

A two-button switch is assembled from two one-button switches, so the connection diagrams for each half are identical.

Connection of the Legrand switch with illumination and indication

An additional lamp in switches is used for the following purposes:

  • Backlight, where it acts as a pointer showing where the switch is located. It lights up when the switch is off. To connect the backlight in Legrand switches (with one or two keys), a phase wire is sufficient.
  • Load indication in cases where the lighting devices are located outside the human visibility zone (shed, pantry, etc.). If the switch is inoperative, the indication lamp does not light up.

The load indication mode is turned on only if not only the phase wire, but also the neutral wire is connected to the input contacts of the circuit breaker.
