ABSTRACT:
A membrane switch provides a substantially rigid front fascia without the need for flexure limiting standoffs or the like. The membrane switch may use thin, printed insulating dots whose pattern controls the force required to actuate the switch elements as a function of distance from the switch elements preventing multiple activations.
