Mankind has been using existing schemes for installing switches for a long time. The first single-gang switches impressed with the ease of installation. Therefore, the appearance of two-button switches was received with interest. But manufacturers of household electrical equipment did not stop there. Now the installation of a pass-through switch for the N-th number of fixtures and lamps is available for a housewife.
How to choose a switch
An obligatory element of electrical wiring, without which it is unthinkable to control the operation of a light source, are switches. The existing set of switches can be classified according to various criteria.
The main types of switches for a private house or city apartment can be distinguished:
By execution - one-, two-key, through
By price, from economy class to luxury appliances
According to the type of electrical wiring used: open or hidden.
The only common feature is the installation of a switch, the circuit of which has not changed for decades. Naturally, for the installation of a switch by oneself, basic knowledge of electrical engineering and skills in working with electrical installation tools are required. By the way, very useful information about the degree of protection of the switch is on the surface of each device.
It is an abbreviation for IP. Let's tell you that for enclosed spaces it is recommended to use switches with a degree of protection IP20, for rooms with high humidity - IP44, and for street lighting of a private house model IP65. Recall that for a certain type of electrical wiring in the house, it is necessary to install an open-mounted or hidden switch, respectively.
Helpful Hints
Before starting the installation of the switch, no matter which one or two-key switch, study the contact diagram on the back cover of the device, which is a guiding star in the world of hand-made wiring.
Here you will see a picture of open contacts in the "Off" position and a common output. For example, a two-gang switch has three contacts. This is one common and two outputs designed to control the inclusion of lighting fixtures.
Before you start “pressing the keys”, it does not hurt to study in more detail the design of the device for subsequent installation.

Classics of electrical installation products - single-gang switches
The most demanded and therefore sold product of the electrotechnical market is the single-gang switch. The high quality and reliability of the unpretentious mechanism of a single-gang switch has gained a halo inside and outside private houses, apartments and industrial enterprises.
Among the advantages of the product is the possibility of open installation for power networks with a rated current of 6A. The principle of operation of a single-gang switch is based on breaking the circuit. Regardless of the number of keys on the device, the switch is responsible for breaking the AC circuit, the functions of which are assigned to the phase wire. In this way, the switch reliably ensures that the luminaire is de-energized and safe operation is ensured.
single switch installation
Affordable circuit breaker installation consists of the following steps:
- We turn off the electricity at the switchboard.
- Remove the outer panel and disassemble the switch.
- We take the mechanism out of the case.
- We apply the switch to the place of the future location (for an open type of electrical wiring) or into an existing installation box for a hidden type of fastening.
- We place the mounting holes at the place of attachment on the wall.
- We fix the housing of the switch socket.
- We put two wires into the switch.
- We remove the insulation and clean the ends of all wires.
- We connect the wires to the clamps or terminals.
- We place the switch mechanism in the installation box.
- We clamp the switch mechanism with the help of "legs" and two screws.
- We assemble the switch and install the top cover.
- We test performance.
No less popular is also a two-gang switch, the principle of operation of which is similar to the installation scheme of a single-gang switch.
Double switch, why we choose double switch
The two-gang switch is two connected switches, united by a common housing. When the corresponding key is turned on, the circuit is broken for the phase wire following to a certain light source.
According to the circuit breaker, the working wire, the neutral wire and the protective conductor, are connected directly to the light source. In this case, the phase passes directly through the switch.
double switch installation
We begin the installation of a two-gang switch according to the installation algorithm, designed for single-gang switching until the wires are connected. Now we determine where each conductor of the switch has phase, zero and ground. Having decided on the rating of the conductors, we make grounding and set up each control wire.
If the switch is of a modular type, then we supply voltage to both switches using a jumper.
Then we continue the connection in the same way as the connection diagram for an ordinary single-key device. We place the phase wires in the phase terminals, the other two wires, each in its own block, in the terminals marked with arrows.
The connected mechanism is placed in the installation box. We fix the mechanism using paws and screws. We adjust the correct placement of the switch according to the level. Then we install the frame in the caliper and install the outer keys.
Having learned how to install a two-gang switch, it's time to connect a couple of lamps in a private house through such a switch. You will feel the convenience of using the switch immediately. In addition, a certain energy savings with the ability to turn on a separate lamp will not keep you waiting.
we connect two lamps through a two-gang switch
To connect 2 lamps according to the connection diagram, it will be necessary to connect the conductors and lighting fixtures in this way:
Distribute the wires by rating in the junction box
Connect a common two-gang switch according to the rules
Connect each lamp separately.
According to the general scheme, there will be five twists in the junction box.
This video will help you connect a two-gang switch.
