The mankind has been using the existing circuits for the installation of switches for a long time. The first one-key switches were strikingly simple. Therefore, the appearance of two-button switches was received with interest. But the producers of household electrical equipment did not stop at the achieved result. Now the installation of a pass-through switch for N number of lamps and lamps is available for the housewife.

How to choose a switch
An obligatory element of the wiring, without which it is unthinkable to control the operation of the 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 a city apartment can be distinguished:
• on execution - one-, two-key, entrance
• by price, from economy class to elite appliances
• by type of wiring used: open or hidden.
The only common feature is the installation of a switch, the circuit of which does not change for decades. Naturally, for the manual installation of a switch, basic knowledge of electrical engineering and skills of working with an electrical installation tool are required. By the way, very useful information on the degree of protection of the switch is on the surface of each device.
This is an abbreviation for IP. We will suggest that for enclosed spaces it is recommended to use circuit breakers with IP20 protection degree, for high humidity premises - IP44, and for street lighting of a private house of model IP65. Recall that for a certain type of wiring in the house, it is necessary to install an open installation switch or, respectively, hidden.
Helpful Tips
Before starting the installation of the circuit breaker, no matter which single- or double-key switchboard is used, examine the contact circuit on the back cover of the device, which is the guiding star in the world of hand-woven electrical wiring.
Here you will see a picture of the open contacts in the "Off" position and the general output. For example, there are three contacts in the two-switch switch. This is one common and two outputs, designed to control the inclusion of lighting equipment.
Before you start "pushing on the keys" it does not hurt to learn more about the design of the device for later installation.
It is accessible and understandable about the installation of pass-through switches and will not only tell this video.
Classic wiring accessories - single-key switches
The most demanded and therefore sold item of the electrical market is a one-key switch. The high-quality and reliable performance of the unpretentious one-key switch mechanism has acquired a halo of habitation inside and outside private houses, apartments and industrial enterprises.
Among the advantages of the product is the possibility of an open installation for electric networks with a rated current of 6A. The principle of operation of the one-key switch is based on the breaking of the circuit. Regardless of the number of keys of the device, the switch is responsible for breaking the AC circuit whose functions are assigned to the phase wire. In this way, the switch reliably ensures the power supply to the light and safe maintenance.
mono-switch installation
The available installation of the circuit breaker consists of the following steps:
- We turn off the electricity on the switchboard.
- Remove the outer panel and disassemble the switch.
- We take the mechanism out of the case.
- We apply the switch to the location of the future location (for an open type of wiring) or to an existing installation box for a hidden type of attachment.
- Place the fixing holes in the place of attachment on the wall.
- We fix the case of the switch outlet.
- We put two wires in the switch.
- Remove the insulation and clean the ends of all wires.
- We connect wires to clamps or terminals.
- We place the mechanism of the switch in the installation box.
- We squeeze the mechanism of the switch with the help of "feet" and two screws.
- We collect the switch and install the top cover.
- We test working capacity.
No less popular is also a two-key switch, the principle of operation of which is similar to that of a single-key switch.
The switch is two-key, why do we choose a two-key switch
The two-key switch consists of two connected switches, united by a common housing. When the corresponding key is turned on, the circuit breaks for the phase wire next to the particular light source.
According to the circuit breaker circuit, the working wire zero and protective conductor are connected to the light source directly. The phase passes directly through the switch.
installation of a two-button switch
Installation of the switch of the two-key is started according to the mounting algorithm, intended for single-key activation until the moment of connecting the wires. Now we determine where each switch conductor has a phase, zero and ground. After determining the conductors rating, we make grounding and adjust each control wire.
If the switch is a modular type, then we apply voltage to both switches using a jumper.
Then we continue the connection in the same way as the connection scheme for an ordinary one-button device. We place the phase wires in the phase terminals, the two other wires each into our unit in the terminals marked with arrows.
The connected mechanism is placed in the installation box. We fix the mechanism using the feet and screws. Correct placement of the switch is corrected by level. Then we set the frame in the caliper and set the outer keys.
Having learned to install a two-button switch, it's time to connect a couple of lamps in a private house through such a switch. The convenience of using the switch you will feel immediately. In addition, a certain saving of electricity with the possibility of switching on a separate lamp will not keep you waiting.
we connect two lamps through a two-key switch
To connect 2 luminaires according to the wiring diagram, you will need to connect the conductors and lighting devices in this way:
• distribute the wires at face value in the distribution box
• connect the common two-key switch according to the rules
• connect each luminaire separately.
According to the general scheme in the switch box there will be five twists.
