Abstract: A device for use in a weapon system provides electrical energy for fuzing the weapon system. The device includes a detonator disposed within a housing, with the detonator being in association with a piezoelectric element such that upon detonation, the piezoelectric element is exposed to sufficient pressure to produce electrical energy. A firing pin mechanism is detachably attached within the housing in a pre-detonation position and is capable of detachment at a selected pressure and movable after detachment to a detonation position, detonating the detonator for the production of electrical energy.
