PROBLEM TO BE SOLVED: To solve the problem that excess switches must be connected in series at a post stage for interrupting a signal from an unintended input terminal because an output terminal for a switching circuit must be connected at either input end in a switch, when one switching equipment is constituted by combining a plurality of the switching circuits in a conventional switching circuit. SOLUTION: The switching circuit has a plurality of unit switching elements, and has a function simultaneously interrupting all unit switching elements. COPYRIGHT: (C)2008,JPO&INPIT
