How to wire a three-way single-control switch? Five holes on the back

Three open single-control switch wiring steps are as follows:

(1) First of all, L12, L22 and L32 are connected to three wires to connect the three switches of the lights.

(2) the firewire connects to the switch A gate L1, L1 and L2 connection, L2 and then connected to L3, so that two circuits can be formed, these two circuits to ensure that when any one of the switch state change, you can make the middle of the electrical appliances connected to the power supply in the open/circuit state switching.

(3) The final connection circuit diagram is shown below.

Three-control switch installation precautions:

(1) with two double switch according to the two switches to control a light method of wiring, and then between the two switches of the two double wire disconnect, with a double knife double connecting switch to connect them, so that through its on and off, to achieve the original two wires back to conduction or cross the conductive, so that the three switches to control a lamp of the circuit will be completed.

(2) Three-control switch can realize the control of lighting in an unlimited number of locations, the principle is that the multi-control switch itself is a 220V AC single-pulse bistable circuit system, the multi-control switch is responsible for controlling the lighting load, the sub-switch is responsible for the multi-control switch to provide pulse signals.
