Abstract:
a pressure actuated switching device, which comprises:a) an insulative cover sheet;b) an insulative base;c) at least one emitter electrode and at least one primary receiver electrode;d) at least one layer of piezoresistive material disposed between said cover sheet and said base and further disposed between said at least one emitter electrode and at least one primary receiver electrode;e) detection means for detecting a shear component of a force applied to the pressure actuated switching device, the detection means including at least one secondary receiver electrode spaced apart from the primary receiver electrode, the detection means forming an electrical closed circuit path between the at least one emitter electrode and the at least one secondary receiver electrode in response to the shear component of the force applied to the pressure actuated switching device.
