特徴とするリミツトスイツチ。 A head supporting a rotating shaft is fixed to one end of the switch case containing the basic switch, and the base end of an operating lever with a roller supported at its tip to detect the object to be detected is fixed to the rotating shaft. A return coil spring that applies a spring force to the flat surface of the rotating shaft via a return plunger is disposed in the head, and the operating plunger for opening and closing the basic switch is operated in response to rotation of the operating lever. In a limit switch in which a driving disc cam is fixed to the rotating shaft, a protrusion is formed on the outer circumferential surface of the rotating shaft or the cam corresponding to the free position of the operating lever, and the protrusion is pressed when the operating lever returns. A limit switch characterized in that an elastic stopper means for braking is provided on the head side.
