ツチ。 A proximity switch used for detecting the presence or absence of an object or as a position sensor, etc., which is equipped with a plurality of detection circuits that are operated individually in the same case, and which is used for detecting the presence or absence of an object or as a position sensor. A failure detection circuit that detects an abnormality or failure and sends a failure detection signal, and a switching circuit that switches the detection circuit from the operating detection circuit to the normal detection circuit based on the failure detection signal from the failure detection circuit. , when an abnormality or failure of the detection circuit that was performing the detection operation is detected by the failure detection circuit,
The detection circuits are sequentially switched from the detection circuit in which an abnormality or failure has occurred to the normal detection circuit by the above switching circuit, and the detection operation is performed by the normal detection circuits in sequence until an abnormality or failure occurs in all detection circuits. A proximity switch characterized in that the proximity switch is configured to continue.
