A widespread and practical electrical installation
The back-and-forth electrical assembly makes it possible to control the electric current of a bulb from two switches, i.e. when you activate one of the switches, it acts on the power supply of the bulb, but without changing the state of the other switch.
We find this type of connection for example:
A stair climb: it would be a shame to have to go back down the stairs to turn off the light
Lights in a large room: practical to have 2 switches for a series of lights
At the bedside table: again, it's still comfortable to turn off the bedroom light from your bed, without having to get up
The Principe of fonctionment
When connecting a simple switch, simply pass the power supply through the switch that will control the luminaire. In the case of connecting switches back and forth, the switches must each be able to act on the light, they will therefore be connected to each other, we will see the details of this type of connection later.
To use more than 2 switches
This very simple type of assembly is limited to the use of 2 switches, no more, if you want to connect more than 2 switches, you will have to start on a remote switch connection instead.
Back and forth connection of a switch
Before you start
Prior to any electrical installation of this type, the electrical conduits must be passed between the connection points you have planned, at the desired locations, lights and switches.
