The blocking disc serving as an explosive train interrupter of a safety and arming mechanism is angularly displaced from its safe position by a stepping motor through reduction gearing in response to timed energizing pulses applied thereto from a crystal-controlled pulse generator. The blocking disc is releasably latched in its safe position by a locking rod controlling the supply and cut-off of energizing voltage to the pulse generator to accurately time displacement of the disc to an armed position.
