<p>PROBLEM TO BE SOLVED: To mitigate abutting impact by a detection body to a stopper by making a detection body touch an actuator protruding to the maximum from a stopper face provided on a housing end face and standing still so that the actuator is pushed and is displaced so as to operate first switch, and operating second switch before the first switch is further displaced to touch a stopper end face. SOLUTION: When a detection body A is moved rightward so as to abut the contact 4a of an actuator 4 and the actuator 4 is slightly displaced rightward, a first moving contact 6 is parted from a first fixed contact 8, and a first switch circuit is turned off via conductors 8a, 5a so that the detection body A is decelerated by this OFF signal. When the detection body A is further displaced rightward so that the left end portion of the actuator abuts and pushes a second moving contact 10 so as to part from second fixed contact 9, a second switch circuit is turned off via conductors 9a, 12a so that the detection body A is stopped or reversing controlled by this OFF signal.</p> |
