The circuit uses optical-isolation optoelectronic thyristor rectifier as high voltage DC switch. When MCA2 photoelectric Darlene Dayton circuit's Q1 divides current of the load through gate, then the silicon controlled rectifier's gate gets bypass, silicon controlled rectifier is turned off. If the pulse signal is added to appropriate light emitting diode, the circuit operates, so that the thyristors are turned on or off.
