Claims

[Scope of Claim for Utility Model Registration] A. A common terminal planted in the center of the bottom of the insulating case, B. Fixed terminals planted on either side or on either side of this common terminal, and C. With the common terminal as a fulcrum. a movable contact piece supported so as to be capable of seesaw movement; a crank lever supported by the case so that the rotating free end engages with the insulating block and the rotating shaft can move on an extension line of the common terminal; F applies a biasing force to the crank lever toward the common terminal; A leaf spring approaches the insulating block by pressing the G button and engages with a pin engagement recess formed in the insulating block through a slit formed in the leaf spring, thereby converting the insulating block and the movable contact piece. A push button switch consisting of an operating pin and a button.
