Abstract

A membrane switch assembly includes a stationary membrane switch circuit layer (16), an insulating spacer (28) or separator on the stationary membrane layer having at least one opening therethrough (30) and a movable membrane layer switch circuit on the other side of the spacer having at least one snap-action tactile element (22) extending upwardly therefrom. The stationary membrane layer has electrical conductors (16) thereon arranged in a geometrical pattern and cooperating with the openings (30) in the separator layer (28) to define an array of unique switch and circuit locations. The movable layer has a conductive contact surface 26 located on the flat surface thereof along the periphery of a tactile element (22), preferably as an annular ring, or as segments. <IMAGE>
