ABSTRACT:
An electric primer for cartridge ammunition is designed to minimize antenna oupling, capacitive coupling, and aperture coupling of stray electromagnetic radiation thereinto to avoid accidental primer detonation with resulting ignition of cartridge propellant. The primer is provided with a button electrode deeply recessed totally behind a small diameter access aperture which physically guards the button electrode from antenna and capacitive coupling while allowing activating plunger entry. Furthermore, the small opening channels stray radiation about its periphery rather than admitting it to the button electrode.
