A piezoelectric lighter, particularly a gas lighter, including a chassis (1), (2), provide with a pressure trigger (4) and a conductor opening (3), a piezoelectric active element (15) oscillating within the chassis, and two electrodes (5) and (18) connected directly to said piezoelectric active element (15). One end of the active element (15) is grounded to the chassis and, through the pressure trigger (4), has contact with the metal opening (3) provided with a semicircular-shaped tongue comprising the first electrode. The other end of the active element (15) has contact with an oscillating metal rod (18) sustained by the insulating support base (13-14) of the same active element (15) able to work as a counter electrode during oscillation and to move facing the first electrode (5). The active element (15) may be a single ceramic piezoelectric element or two ceramic elements set opposite each other. |
