ABSTRACT:
A link member consists of a set of frame bodies assembled in an X shape when seen from the side so as to be swingable each other. A base member is provided to support the link member. At least one of the link member and the base member is an elastic member which is interposed between a key top member and the opposed switch members. A springback force is obtained by the elastic member to restore the key top member and the link member to their original positions. Thus, the number of resin components is reduced. A push button switch reasonable in cost and low or short in size is provided.
