Electrical priming of a firearm primer

A primer for a personal firearm, the primer comprising:

• a primer cup including a cylindrical side wall closed at one outer end by a bottom;
• a pyrotechnic charge placed in the primer cup;
• an electrical component configured to produce thermal energy to ignite the pyrotechnic charge, the charge being in contact with the electrical component;
• and
• a printed circuit board including an inner face comprising the electrical component in contact with the pyrotechnic charge;
• wherein the printed circuit board forms at least in part the bottom of the primer cup, wherein the printed circuit board comprises a conductive annular portion, and wherein the primer cup is in electrical contact with the printed circuit board via a conductive washer abutting against the conductive annular portion and against a corresponding portion of an inner surface of the cylindrical side wall of the primer cup.
