ABSTRACT:
The piezoelectric ignition mechanism of the present invention has a telescopic assembly having an inner and an outer members aided by a return spring for maintaining a maximum extension between the members. The inner member includes a piezoelectric element which is immobilized between an anvil and impact pad over which a plexor strikes to generate a spark. An impact spring for aiding the plexor is guided in the interior of the telescopic assembly and is disposed between the plexor and an end member connected to the outer telescopic member. A resistant spring is also disposed at or near the end member to provide additional resistance to the operation of the piezoelectric mechanism in order to discourage the undesirable operation by young users.
