ABSTRACT:
Pressure sensitive resistor elements are provided which serve as an on-off switching device and comprise an anisotropically electroconductive sheet which is formed of an insulating rubbery elastomer as a matrix within which many electroconductive fibers are dispersed and oriented in a direction substantially perpendicular to the plane of the sheet, an electrode provided on each surface of the sheet, and an insulating layer interposed between at least one of the electrodes and the sheet. The resistor elements can remain insulating in the absence of a compressive force between the electrodes and contribute to electric conduction in the presence of the compressive force.
