1. A fuze assembly for attachment to a projectile including a casing, a booster charge and a means for firing said booster charge in said casing; an acceleration energized electric energy source for said firing means comprising, an inertia mass slidably mounted in said casing, a first electrical terminal supported rearwardly in said casing, a piezoelectric element mounted between and in contact with said first terminal and said inertia mass, a second electrical terminal for contact with said firing means, said second terminal being secured forwardly in said casing; and a means for building up an electrical charge across said piezoelectric element comprising, a first resilient contact secured on said first terminal and being normally out of contact with said casing and a second resilient contact secured on said second terminal, said second resilient contact being in constant contact with said inertia mass, and being normally out of contact with said casing said inertia mass moving rearwardly upon projectile acceleration to energize said piezoelectric element and whereby said first and second resilient contacts upon maximum projectile acceleration contact said casing thereby shorting out said electrical charge built up across said piezoelectric element to said casing, said first and second resilient contacts resuming out-of-contact positions with respect to said casing upon reduced projectile acceleration.
