Abstract
A semiconductor switch circuit includes a switching transistor circuit having switching transistors connected in two stages, a follower circuit comprising a condenser for integration, a power source circuit, the switching transistor circuit connected between the follower circuit and the power source circuit, and a switching transistor connected as the second stage of the switching transistor, circuit such that each of the base and the emitter of the switching transistor is connected to a resistor and the resistor is connected to an output terminal of the follower circuit for generating an output whose level equals the level of the collector of the switching transistor.
