a current limiting transistor whose output is rectified commercial alternating current power is applied to the collector via a fuse; a first transistor whose emitter is connected to the emitter of the current limiting transistor and which receives the output power from the collector; a second transistor in which a core-free emitter current path is connected between the base plate and ground; a bias circuit that applies a bias generated using the rectified output to the base of the second transistor; and this bias circuit. a third transistor having a collector-emitter current path connected between the current limiter and ground and capable of controlling on/off of bias; and a Zener diode that detects an abnormality in the emitter potential of the current limiting transistor and applies a bias to the third transistor. A switch device for a power supply circuit, characterized by comprising a circuit.
