This spring-actuated ball-retained striker device is in a metal case, the lower end of which is threaded and protected by a transit cap. The two retaining balls are held in place by a pin fitted into the hollow upper end of the striker. This pin, with its pull cord, is held in position by coiled spring and drilled to receive the safety pin that passes through it and the case.
It is used primarily for boobytrapping metallic antitank mines and for fuzing the Model 1952 trip flare.
No information about functioning.
