るタイムスイツチ。 A projection is provided on the shaft, and a cam having an engagement recess that engages with the projection and a shaft insertion hole is rotatable by rotation of the shaft, and the force of thrust movement of the shaft is received by the fixed member via the projection. In the time switch, a circular groove is formed on the outer periphery of the shaft insertion hole on the fixed member side of the cam, and a portion of the groove facing the engagement recess is a through hole; is provided with a rib through which the protrusion cannot pass through, and a protrusion receiving member is slidably fitted in the groove, so that the force of thrust movement of the shaft is received through the protrusion receiving member. Time switch.
