How to connect a two-gang switch: diagram, video - Asutpp

Single-key switches are less and less used in modern apartments with three- or five-lamp chandeliers. We offer to consider how to connect a two-key switch with backlight, with a socket, as well as a photo and diagram in our article.

Types of switches

There are two ways to connect the wires to the light switch: screw terminals and self-locking terminals. In the first case, the cables are placed in a special block and tightened with a screw. The only drawback of such a connection is that over time the screws unwind and need a tightening. Those. a mini-circuit may occur at any time.

Large manufacturers use the second option to create their products. It is considered more expensive, but also has greater efficiency. In addition, recently, more and more often began to use modular technology.

How to connect a switch

Below we presented the circuit diagram of the circuit breaker and its installation. The two-key euro-switch is two single devices, but in one case. Their phases are combined, and at the moment when one of the contacts bridges (and he begins to supply power to his group of devices), the second breaks the circuit, and stops receiving signals from the phase cable from the outlet or wiring to apartment. This happens because the ground wire and phase zero are connected directly to the luminaire, and the phase passes through the switch.

For work you will need:

  1. Pliers;
  2. Screwdrivers (indicator, flat and cross);
  3. Stationery knife;
  4. Level.

Initially turn off the electricity. Next, you need to prepare the wires in the installation box, for this we clean them with pliers. It is necessary to leave about 10 centimeters of wire, cut off the excess with a clerical knife. Now you can connect the wiring and the wires of the switch. If the wiring is three-phase, then this process will not be difficult. 6 just connect the corresponding cable colors to 3 phases and zero.

If the wiring is two-phase, then you need to fasten the switch wires with a terminal, and as a result, get two jokes instead of three, connect them to the power supply.

Install the protective plates and turn on the power. Ideally, both switches should be in the up or down position when the light is off. If necessary, remove the second electrical switch, rotate it 180 degrees in the box, then set it as the two positions of the toggle switch.

Connecting a chandelier is also not more difficult. Certain lamps are combined into groups, and if there can be only two groups, then there are any number of lamps: with two horns, five or even six.

Circuit breaker installation

The main difficulty is not connecting the wires to two independent lamps. And in the installation of the switch in the junction box. Imported circuit breakers (simon, wessen, lezard, schneider electric, anam, legrand-legrand, valena).

Using a screwdriver, it is necessary to fix the switch directly in the installation hole and tighten it with screws or bolts (which are most often supplied). After we install not the box with the keys, press and fasten (if necessary), bolts on top.

A very interesting practice is the installation of a switch with an indication of a hidden installation. This type of electrical appliance is popular in the “smart” house and in the apartment, where design and style play a big role. Its installation is carried out in a recess in the wall, from the junction box to the wiring cables, everything is completely similar to the usual installation, but at the final stage you need to attach a special lockable cover (sometimes sensors are used with a flip damper).

Consider the installation process if there are two electricity networks. We unite one network - in one group, the second - in another. Now we connect the cables accordingly. One wire should close when the other opens, so check the connections carefully.

One switch for two lamps

As already mentioned, the devices control two groups of fixtures, which means that you can install the bathroom and the corridor on the two-gang switch. To do this, we lead the wires from both lamps to the wires and the location of the switch, combine each of them into separate groups, connect with terminals and attach to the switch. For large rooms, we recommend reading the article on how to connect a two-gang switch through passage.

In the same way, the lighting switch is installed in two rooms.

Installation Tips:

  • unite groups thoughtfully (for example, a kitchen-toilet, a corridor-bath, a living-room, etc.) then there will be no cable overrun;
  • install switches in reach zones: not behind a chair or cabinet;
  • a more powerful switch must be connected to the lamp and fan, given that in addition to the main cables, there is a wire that is responsible for powering the fan itself;
  • we recommend using switches with simon indication;
  • in order to properly connect the device, it is necessary to look at the wiring, especially when connecting to two power sources;
  • If you have not had such an experience before, we recommend that you preview the video how the switch is installed.
