The 3 wires (fire, zero, ground) of the torsion switch are connected to the socket, and if it is two fires and one ground, it is connected to the double switch. Two fires one connected to L1, one connected to L2, L11, 122 series connection after the pressure zero line general switch of the installation hole.

The two feet in the middle are connected to the line, and the two ends of the line are closed, one is the same direction as the button, and the other is the opposite, and it should be checked with an electric meter.

Button switches sometimes need to control the input and output of current in a large current, so the quality of the button switch and all aspects of the requirements must be very guaranteed.
