Abstract

An electrical switch (100) may comprise a base (130, 130') having three electrical conductors (132-136) thereon and an electrically conductive flexible dome (150) adjacent the base (130, 130'). The flexible dome (150) has plural longer legs (154) extending from its dome (152) and in electrical contact with a first conductor (134), has a shorter leg (156) extending from its dome (152) and overlying a second conductor (136), and has its dome (152) overlying a third conductor (136). A pushbutton (190) must be moved over a distance substantially greater than an actuation distance of the flexible dome (150) to apply sufficient force to cause the shorter leg (156) to contact the second conductor (136) and the dome (152) to contact the third conductor (136). A spring (180) between the pushbutton (190) and the flexible dome (150) couples force to the flexible dome (150).
