。 In a switch input circuit for a control device using a microcomputer 1, the operation "on" input ports of multiple microcomputers 1 are connected to the operation "on" switch 2, and the operation "on" input ports of multiple microcomputers 1 are connected to the operation "off" switch 3. Connect the operation ``off'' input port and have the microcomputer 1 judge that the operation ``on'' switch 2 has been pressed only when a signal is input to all the operation ``on'' input ports. 1. A switch input circuit characterized in that if a signal is inputted to at least one of the plurality of operation "off" input ports in the operation "off" input port, it is determined that the operation "off" switch 3 has been pressed.
