Abstract
A safe/arm explosive delay path for detonating an explosive device and prnting detonation of the explosive device by extraneous factors present in the internal environment. The delay path comprises a detonator and first explosive trail leading to a delay explosive trail composed of explosive material and reactive material. A second explosive trail is connected to the first explosive trail and parallel to the delay explosive trail. The delay trail and second explosive trail terminate in an explosive junction. The explosive junction or explosive switch is a gated diode with the delay trail leading through the diode in the second explosive trail functioning to gate the diode. The gated diode allows a detonation wave propagating through the delay tail to proceed to the explosive device only when a detonation wave has propagated along the second explosive trail and gated the explosive diode prior to the arrival of the delay detonation wave. The delay trail is composed of a mixture of explosive and reactive material such that the detonation velocity is 1/2 to 1/10 the velocity of ordinary or secondary explosive.
