ABSTRACT:
An interrupter in a pyrotechnic system for selectively arming or disarming a detonation propagation transfer line comprises a mechanism for driving a barrier to and from safe and arm positions using safe and arm actuators. The motion of each of the actuators is damped to prevent cycling from external transient forces. A safety mechanism comprises a mediate member slaved to the drive mechanism and a lock member. A safing key is inserted into the interrupter to drive the lock member into a position which limits the motion of the mediate member whereupon an attempt to drive the barrier from a safe position will be blocked by the lock member. The safing key will be captured in the interrupter such that it cannot be removed until the barrier is returned to the safe position. In the preferred embodiment, the barrier comprises a rod having a non-circular transverse slot disposed between the line segments.
