ABSTRACT:
An apparatus for a hinged key switch is presented which operates around a hinged pivot point located external to the four points of the key cap, and which comprises a rubber spring providing a vertical bias and an arm with an extension which acts as a stopper when it abuts a raised portion of the mounting plate. The rubber spring is integrally formed from a rubber sheet which is supported on one side by the mounting plate and on the other by the back plate. The stopper extends vertically downward from the key cap and acts to limit the movement of the key in the vertical direction. A horizontal extension from a lower portion of the key cap further extends downward and through a slot in the mounting plate and has a hook which abuts an underside of the mounting plate, such extension from the key cap acting as the pivot point around which the key rotates.
