ABSTRACT:
An electric primer using an intrinsic conductive pyrotechnic mixture is improved by the addition of a carbon layer between the inner and outer electrodes and the mixture. The carbon layer provides a parallel resistive current path between the electrodes in addition to the path through the conductive mixture. The addition of a carbon layer also increases the operable temperature range of the primer. The high energy firing threshold of the intrinsically conductive pyrotechnic mixture and the additional dissipative current path through the carbon layer coact to further reduce the sensitivity of the primer to RF radiation and ESD hazards.
