ABSTRACT:
An a.c. switch has two pairs of diodes each of which has two diodes connected in back-to-back relationship between the signal input and output of the switch. The two pairs of diodes are connected in parallel with each other in opposite senses. A MOSFET transistor is connected between the junctions of the two diodes in each pair. A switching control unit controls switching of the transistor such that, when the transistor is conducting, signal current flows between the input and output via one diode in one pair, the transistor, and one diode in the other pair. When the transistor is not conducting, current flow between the input and output is blocked.
