Abstract
A main thyristor is serially connected to a load across an AC source. A thermally sensitive thyristor is connected at the anode to the anode of the main thyristor through a resistor and at the cathode to the gate electrode of the main thyristor and responds to an ambient temperature exceeding a predetermined magnitude to be conducting. When conducting, the thyristor switches the main thyristor to its ON state. Alternatively, the anode of the thyristor may be connected to the junction of two series resistors connected across the anode and cathode of the main thyristor. The conducting thyristor turns the main thyristor off.
