ABSTRACT:
To facilitate assembly of a piezoelectric igniter the hammer is formed in one piece with diametrically opposite lugs and the interfitting parts of the spring-receiving sleeve and the casing containing the piezoelectric crystal activated by the hammer are of noncircular cross section with a major transverse dimension greater than the free end spacing of the lugs which is, in turn, greater than the inner window separation of the sleeve.
