Abstract: A common contact and at least one fixed contact are planted on an insulating bottom panel of an insulating case. A movable contact piece formed by bending a conductive spring material into a U-shape to have a pair of opposed contact leaves is pivotally mounted on the common contact so that it is turned from side to side by an actuator such as a push button or toggle lever. As the movable contact piece turns from one side to the other, it makes sliding contact with the fixed contact gripping it between the pair of opposed contact leaves.

Abstract: A toggle switch comprises a casing including a bottom plate of an insulating material through which extend a common terminal as well as first and second transfer terminals. A rod-shaped movable contact member is retained on the common terminal intermediate its length for seesaw motion for causing the movable contact member to contact the first and the second transfer terminals alternately. An interposing piece of an insulating material is disposed on the movable contact member and is engaged by a pusher which is resiliently urged toward the terminals and is displaced toward the first or the second transfer terminal relative to the common terminal under the control of operating means. Such operation produces the seesaw motion of the interposing piece and the movable contact member.
