Abstract
A spark igniter circuit is provided for igniting a flammable gas mixture in devices such as gas torches, lanterns, stoves and the like. A piezoelectric spark generator imposes a voltage on an electrically conductive circuit which is discontinuous in two locations for creating a pair of spark gaps in the circuit. The first spark gap eliminates the need of stripping insulation from a pair of wires and providing a connector therebetween and possibly enhances the effectiveness of a spark at the second spark gap for igniting the gas mixture.
