Abstract
A piezoelectric igniter with a manually operable striking mechanism which comprises a hammer, a piezoelectric transducer, and an energy storing or compression spring acting on said hammer. The hammer is held in its rest position by a release device adapted to release the hammer when a definite compressive force is developed in the compression spring. A bounce plate is mounted at the end of the transducer facing the hammer and a return spring is provided between said bounce plate and said hammer. The transducer has a lateral clearance to a housing which receives all component parts.
