ABSTRACT:
An improved actuation device for a piezoelectric lighter having an axially aligned hammer and a piezoelectric impact terminal. An elastic retention member engages the hammer as a bias force is imposed thereon. The actuation member is adapted to release the hammer by a displaceable actuation switch after the hammer passes through a predetermined distance thereby causing the hammer to strike the piezoelectric impact terminal.
