ABSTRACT:
A static electricity discharging device used in a switch for an electrical equipment includes a push button movable into and out of an operative position so as to operate the switch of the electrical equipment, and an elastic member normally maintaining the push button out of the operative position, the elastic member being elastically deformable by the push button when the push button is moved to the operative position. The static electricity discharging device also includes an electrically-conductive layer disposed on a surface of the elastic member, the electrically-conductive layer being electrically grounded whereby external static electricity applied to the push button is passed directly to the ground through the electrically-conductive layer.
