Abstract
In a latch with a switch, when a movable member is pushed into a housing against a force of a coil spring, the movable member is locked in a pushed-in position by a lock mechanism and a switch is turned on. When the movable member is pushed again into the housing, the movable member is returned to a protruding position and the switch is turned off. The switch is formed of a pin attached to the movable member and having both ends protruding from two opposite sides of the movable member; and a pair of fixed terminals fixed inside the housing. When the movable member is at the protruding position, both ends of the pin become a conducting state, and when the movable member is at the pushed-in position, both ends of the pin become a non-conducting state. The conducting and non-conducting states can be reversed.
