In detonator ignition circuitry, reliability is enhanced by significantly increasing the ignition energy voltage. Application of the high voltage ignition energy to the detonator is accomplished through a breakdown device which passes the ignition energy to the detonator only when the voltage thereof reaches its conductive threshold. To avoid the complications of high voltage design in the preferred embodiments, the ignition energy is stored at less than that threshold voltage and is boosted thereto when detonator ignition is desired.
