description:

If you need to control one lamp in two places, you usually need three wires and you need to use a single-pole double-throw switch. The control pole of the triac can be turned on regardless of the forward voltage or the reverse voltage. With this function, the double switch can be realized, and the two grounds can be controlled on the original line. See the PDF for the circuit diagram of the two switches constructed with bidirectional thyristors!
