Abstract

A safety device for an electrically operable projectile fuse in which a primer pin in the form of a firing pin is axially displaceable in the projectile while a detonator cap near one end of the primer pin is adapted to be ignited by impact of the primer pin thereon. A spring biases the primer pin away from the detonator cap while a propelling charge near the other end of the primer pin is electrically ignitable to drive the primer pin into impact with the detonator cap. The primer pin is latched in the projectile with the spring compressed and rotation of the projectile in flight will release the latch. When the primer pin is released it bridges a pair of contacts and completes a circuit from a piezo electric crystal through the propelling charge whereby the projectile will detonate upon impact by igniting the propelling charge and driving the primer pin into impact with the detonator cap. The detonator cap moves into registration with the primer pin in response to rotation of the projectile in flight.
