ABSTRACT:
A push button switch including a key top supported on first and second crossed arm members, each arm member including a first shaft provided at one end and rotatably connected to the key top and protrusions provided at the other end and slidably rotatably received in receiving slots formed in a baseplate. The first and second arm members are joined at central portions thereof such that when the key top is pressed toward the baseplate, the first and second arm members collapse into a common plane. The first and second arm members include parallel legs respectively connected to opposite ends of the first and second shafts, and one of the first and second arm members includes a centrally-disposed manipulating member extending to contact an upper surface of an elastic member, the elastic member being positioned over a switch mechanism. The key top is supported such that it is movable up and down while remaining parallel to the baseplate.
