ABSTRACT:
A firing circuit for use in booby traps providing four different operatio modes. A capacitor stores energy which is discharged through an electrical detonator upon the activation of a silicon controlled rectifier. The silicon controlled rectifier is activated by transistor circuitry in the event of supply voltage depletion or the physical parting of a break-wire by a target. It is also activated by a delay-timer for timed self-destruction and by circuitry responsive to vibrations in the firing circuit generated by the target.
