ABSTRACT:
Individual switch actuators are formed by etching offset grooves in opposite sides of a thin metal plate. The groove on one side of the plate falls just within the groove on the other side of the plate. A web is formed between the adjacent groove walls which provides significant localized flexibility. A discrete contact pad is defined on the inside that is in the plane of the metal plate.
