Abstract
An electrical switch may comprise a base having three electrical conductors thereon and an electrically conductive flexible dome adjacent the base. The flexible dome has plural longer legs extending from its dome and in electrical contact with a first conductor, has a shorter leg extending from its dome and overlying a second conductor, and has its dome overlying a third conductor. A pushbutton must be moved over a distance substantially greater than an actuation distance of the flexible dome to apply sufficient force to cause the shorter leg to contact the second conductor and the dome to contact the third conductor. A spring between the pushbutton and the flexible dome couples force to the flexible dome.
