ABSTRACT:
A small-sized switch has a casing in which a movable contact member engages a first terminal and extends toward a second terminal having a fixed contact. The movable contact member includes an integral arcuate leaf spring extending from the end adjacent to the second contact toward the first contact, the movable contact member having a movable contact. An actuator is mounted on the casing for movement into and out of the casing. The switch also has a rocker pivotably disposed in the casing and held in engagement with the actuator. The leaf spring has a free end engaging the rocker. When the actuator is moved into or out of the casing, the rocker is turned thereby to cause the portion thereof engaging the leaf spring to traverse a line passing through the portion of the movable contact member engaging the first terminal and the movable contact, whereupon the movable contact on the movable contact member is snapped into or out of contact with the fixed contact on the second terminal.
