Abstract : The patent describes a circuit for providing a predetermined time delay after missile impact before detonation, and a self-destruct system controlled by the missile's operation. The circuit uses a quad inverter fed by the self-destruct system and the delay contact system, in parallel, driving a firing system. The contact delay system is basically a one-shot multivibrator, using pulses from piezoelectric crystals as inputs, and having an RC timing circuit to trigger the firing system. The self-destruct system uses a reduced voltage resulting from an extinquished gas generator to trigger the firing system. The firing system has an SCR gatr triggered by the quad inverter output.
