ABSTRACT:
A piezoelectric igniter, especially for lighters, with a striking mechanism comprising a hammer which is movable towards a piezoelectric transducer and which co-operates with an energy storing spring which can be compressed by an actuating member. The striking mechanism has a release means comprising a permanent magnet co-operating with the hammer such that the hammer is held in its rest position by the attractive magnetic forces of the permanent magnet and is released if the energy storing spring has been compressed by the actuating member to such an extent that the spring force exceeds the attractive force of the permanent magnet. The hammer is accelerated by the energy storing spring towards the piezoelectric transducer and impinges on said transducer to generate an electric pulse which is led to a spark gap arranged adjacent a gas discharge valve of the igniter.
