A membrane key switch includes a single resiliently deformable dielectric membrane with flaps cut therein which is formed in a housing such that the end of each flap covers a portion of the membrane. Conductive traces of the membrane are positioned so that downward flexing of the flap, caused by actuation of the switch, establishes electrical contact between a contact region on the flap end and a contact region on an uncut portion of the membrane.
