    Abstract: 1. A condition responsive electronic firing circuit responsive to a predemined change in supply voltage comprising:A first switch means normally biased for conduction,A second switch means including a controlled rectifier normally biased for non-conduction, wherein the gate electrode is responsively connected to said first switch means whereby a change in the conductive state of said first switch effects a corresponding change in the conductive state of said second switch;A detonator connected between one of the output electrodes of the controlled rectifier and a source of power whereby a detonating current passes therethrough when the rectifier becomes conductive;A bypass capacitor connected between the gate and the other rectifier output electrode for preventing inadverent actuation of the rectifier by spurious signals;A zener diode interconnecting said first switch means and a source of power;A storage means connected across the output electrodes of said controlled rectifier to provide a discharge pulse to said detonator upon the initiation of conduction in said controlled rectifier.
