ABSTRACT:
An impact mechanism for piezoelectric transducers, particularly intended for lighters, is described. It consists of an outer housing of plastic material, at the bottom of which the piezoelectric crystal assembly is secured. Slidably arranged within this housing is a support member which contains the impact elements, namely, a permanent magnet, an actuating spring, and a ferromagnetic hammer in magnetically-locked relationship. Slots in opposite sides of the frame member permit a pin to pass through a bore in the magnet and also through the outer housing to which the pin is secured. The frame member, being closed on top, also houses a return spring. The sliding movement of the frame member within the housing compresses the actuating spring and forces separation of the hammer to strike the piezoelectric transducer.
