Abstract
A piezoelectric spark generator comprises a rolling cam of rectangular cross section, the large side of which amounts to 0.08-0.15 times the effective length of the piezoelectric cartridge and in which the angle of inclination of the diagonal exceeds by 3.degree.-6.degree. the angular stroke of the actuating lever. The small longitudinal faces of the cam rest in grooves in the cooperating blocks. The frame is a piece of sheet steel folded to U-shape. The cam protrudes to the outside through opening in the branches of the frame. A portion of the edge of each opening is shaped to provide an end stop for the actuating stroke of the actuating lever.
