ABSTRACT:
An electrical touch switch having a printed circuit baseboard with two circuit patterns electrically isolated and spaced a predetermined distance from one another has a contactor having a resiliently flexible substrate with a plurality of small contactor dots positioned randomly with respect to the circuit patterns, each contactor dot is sufficiently large to span across the spacing between the circuit patterns and depression of any one of these dots against the circuit patterns will provide continuity between the circuit patterns; the contactor substrate also has embedded structural fibers which span across the contactor dots.
