Abstract:
A key switch includes a switch provided on a base, a key top for operating the switch, and a link mechanism supported on the base and supporting the key top on its upper side, a shape of the link mechanism being changed when the key top is depressed. A movable plate is provided on the base, in stacked relationship; such that the movable plate is moved when the key top is depressed so as to change the shape of the link mechanism to a flat shape. An auxiliary link mechanism has a first part supported on the moveable plate and, in turn, by the base and a second part supporting the key top.
