Electronic firing

Electronic firing refers to the use of an electric current to fire a cartridge, instead of a percussion cap.

In modern firearm designs, a firing pin and percussion cap are used to ignite the propellant in the cartridge which propels the bullet forward. The firing pin must travel a short distance, creating a short delay between the user pulling the trigger and the weapon firing, which generally decreases accuracy.

In an electronic-fired firearm, however, an electric current is used instead to ignite the propellant, which fires the cartridge.[1]

Electrically primed small arms cartridges retain the primer which functions in the same way as a conventional primer. Rather than being struck by a firing pin or equivalent mechanical means, a small electric current serves to detonate the primer which provides the thermal impulse necessary to ignite the propellant which then deflagrates, producing pressure.
