Abstract
A piezo film switch comprises a cantilever with a pair of layers, including a piezo film layer and a flexible, backing layer laminated thereto. The piezo film layer produces a positive or negative output pulse, depending upon a direction of deflection of the cantilever. Interface circuitry coupled to the piezo film layer is powered by the output pulses and provides 'pseudo contact closures' which emulate the operation of a mechanical switch.
