摘要
An electrical switch has a pair of fixed contacts (5,5') which are engaged alternately by a moving contact (8) mounted on a strip carrier (7) that is loaded by a coil spring (15). The end of the carrier sits in a 'V' groove in a contact connection (10). The movable contact carrier changes position with a snap action when the end of the spring is displaced to move the force line of action through dead centre. The actuation is provided by a plunger (20) that is displaced by a lever (23). The end of the lever has a hook shape that locates in a groove (29). A projection (36) provides a latching surface. ADVANTAGE - Allows actuator lever to be subsequently installed into a pre-assembled switch.
