Abstract
A safe and arm device for a fuze wherein the safe and arm device does not require stored energy and is activated by a solenoid operating on a pawl mechanism. The pawl in turn pulls a plunger against a detonating chamber in a ratchet-like manner. As the plunger is pulled towards the detonating chamber, a spring stem is compressed thus applying a force against the detonating chamber. Initially, the detonating chamber is locked in a safe position. After the pawl has pulled the plunger into compression against the detonating chamber, a lock on the detonating chamber is released and the detonating chamber pivots into an arm position. This allows a detonator within the chamber to detonate the fuze.
