ABSTRACT:
A piston, backed by a resilient disc, both slidable within a cylindrical case, is provided, on its leading end, with a penetrable conductor pellet, sheathed within an insulator cap. Upon firing of an explosive charge of disc form, arranged behind the piston with a polyethylene disc interposed between the charge and the piston, the latter will be driven forwardly against a pair of piercing points on the ends of a pair of conductor wires mounted in an insulator header in the leading end of the case, the driving force of the explosion being sufficient to cause the conductor wire points to pierce entirely through the insulator cap and to become embedded in the conductor pellet, thus closing a circuit across the conductor wires. A fusible bridge wire, embedded in the explosive charge, is fused by application of an electric current to a pair of conductors extending through an insulator header in the rear end of the case, the forward ends of these conductors being embedded in the explosive charge, and the fusible bridge wire being attached to these forward ends within the explosive charge, in bridging relation to the ends of these conductors.
