Abstract:
1. A safety and arming device, comprising: a substrate; a frame fixed to the substrate, the frame including a travel slot, a head socket, first and second gas expansion chambers having respective first and second nozzles, and first and second safety catch surfaces disposed adjacent to the respective first and second nozzles; a slider translatably disposed in the travel slot in the frame, the slider including a latching head operable to latch in the head socket in an armed position of the device, a storage cavity for storing an explosive charge, first and second cantilevered arms disposed axially apart from each other and angled outwardly from the slider, and first and second deactivation cavities disposed adjacent to the respective first and second cantilevered arms; and a spring that biases the slider away from the head socket; wherein, in a first safe position of the device, an end of the first cantilevered arm contacts the first safety catch surface to thereby prevent translation of the slider toward the head socket and an end of the second cantilevered arm is spaced apart from the second safety catch surface.
