1. A printed circuit board switch comprising a housing having a cavity therein with a side opening, a cavity base, a planar printed circuit board having an end segment and a side extension, means forming spaced apart electrical conductor strips on said end segment and said side extension, means for electrically insulating said strips from each other and said housing, said end segment being juxtaposed with said cavity base and having a planar extent substantially congruous with that of said cavity base, said side extension being directed through said side opening for electrical connection of said conductor strips external of said housing, an electrically conductive contactor plate with straight unbent ends located within said cavity having a center pivot and contact ridges formed on said straight unbent ends thereof, a flexible pad of foamed electrical insulating material secured to the underside of said contactor plate and juxtaposed against said end segment to electrically insulate said plate from said conductor strips and actuator means bearing against said contactor plate to produce a neutral position compression of said pad, said actuator means being operative to shift said contactor plate into first and second pivoted positions to cause said contact ridges thereon to initially contact and then shift laterally of said conductor strips to produce a wiping action thereacross said pad yielding in shear to accommodate said lateral shift and in compression to produce an unbalanced force on said contactor plate for return thereof to a neutral position when said actuator means is released.
