Abstract
This invention provides a safing and arming mechanism for a fuze for a spinning projectile including a ball rotor journaled for rotation within a cavity in the fuze. A firing pin, said cavity and a booster charge lie along the longitudinal axis of the fuze. The rotor carries a stab sensitive detonator in its diametral bore. A first spring mounted on a first seat cut into the ball normally fixes the ball with the detonator, out of alignment with the longitudinal axis of the fuze. A second spring mounted on a second seat cut into the ball also fixes the ball out of alignment. To release the ball, the first spring must be shifted aftwardly by setback force to a third seat cut into the ball, and the second spring must be enlarged by centrifugal force and removed from said second seat.
