Nowadays, the use ofdouble switch. Indeed, because with this technology you can use a beautiful chandelier with several lamps or spotlights, which, undoubtedly, is very convenient when adjusting the optimal lighting.
The junction box includes two wires,red and blue. The first is the phase, and the second is zero. The red wire connects to the same color wire in the junction box, and then goes to the common node of the double switch, which, in turn, comes out yellow and orange.
The ultimate goal of the yellow cable is to come tothe first group of light bulbs, and orange - respectively, the second. They are responsible for regulating all lighting. It turns out that the circuit for connecting a double switch is quite simple and easy to understand. The picture ends with a blue cord (zero), which is always fed to all groups of luminaires, unlike other wires, with which the switch coordinates only the phases of the groups. All these features once again prove the practicality of a double switch.
The sum of all cables inthe junction box is eight: two with an electrical panel, three switch outputs and three light bulbs. However, there may be cases when the number of wires is even greater, for example, when the luminaires are located in different places - the corridor and the bedroom. The zero wire should be connected everywhere, and therefore, with this placement it is twice as large.
The scheme of connection of a doublecircuit breaker is provided with TN-C grounding system. It can differ in type, and can also be represented in TN-S or TN-C-S mode. These types are designed to create additional electrical safety.
In turn, the switches themselves existbig choice. The device can once again emphasize the individuality of the host. They differ in design, color, can be backlit, switch without noise and stuff.
The circuit for connecting a double switch is quite simple and very convenient to use. It allows you to adjust two groups of illuminators, which can contain several bulbs.
