Abstract

Provided is a latch incorporated with a switch, which can be produced at low cost by using a movable terminal which is able to be made inexpensively. The latch L comprises a housing (11), a movable member (41) and a coil spring (61). The movable member (41) is biased by the coil spring 61 toward a protruding position where a part of the member (41) protrudes from the housing (11). As the movable member (41) is pushed into the housing (11), the lock unit is set in a locked state, the movable member (41) is locked in the push-in position, and the switch turns off. When the movable member (41) in the push-in position is pushed again into the housing (11), the lock unit is set in the unlocked state, the movable member (41) returns to the protruding position, and the switch turns on. The characteristic of the latch L is that the switch is consisting of a pin (81) and a pair of stationary terminals (31), the pin (81) being installed in the movable member (41) with its both ends protruding from the opposite two side surfaces of the movable member (41), the pair of stationary terminal (31) being fixed within the housing (11), and two ends of pin make contact with each other to become connecting state when the movable member (41) is in the protruding position, while the movable member (41) is in the push-in position, the two ends of pin (81) break contact to become unconnecting state.
