Abstract:
1. A switch supervisory device connected to an instruction path that connects a microcomputer for controlling a controlled object with a switch used to set the instruction path in a conductive state or a non-conductive state, the microcomputer operating in an operation state including a normal operation state and a waiting state, an instruction signal being sent to the microcomputer through the instruction path during the conductive state so as to change the operating state of the microcomputer to the normal operation state from the waiting state, the device comprising: a path judging block that judges, based on the operation state of the microcomputer, whether or not the switch has set the instruction path in the conductive state, the path judging block being structured so as to judge in response to the operation state of the microcomputer that the switch has set the instruction path in the conductive state; and a signal sending block that
