<p>PROBLEM TO BE SOLVED: To provide an automatic switch which can be fixed to a wiring duct and can be easily disposed at a position where the wiring duct is disposed by providing means for fixing a switch body incorporating a hot-wire sensor for detecting a human body and a switch for turning on or off a load based on a detection output of the hot-wire sensor at a fixing opening formed at the wiring duct. SOLUTION: In an automatic switch A with a hot-wire sensor, a switch body 3 is embedded in a fixing opening 2 formed at a wiring duct 1 disposed from the wall surface of a room toward a ceiling surface, and a light receiving portion of a hot wire is exposed inward the room. The automatic switch A is formed in such a width as to be inserted into the opening of a case body of the wiring duct 1. In fixing the switch body 3 to the case body, the switch body 3 is covered with a holding plate having a pair of positioning pieces, and further, with a fixing frame, through which a fastening screw is screwed to the holding plate. Consequently, it is possible to fix the switch body 3 to the case body.</p> |
