Abstract
A firearm including a barrel having a combustion chamber for receiving propellant and at least one projectile, includes an electrically switched propellant igniting element disposed within the chamber for igniting propellant dispensed into the combustion chamber. A trigger switching assembly, electrically coupled to the igniting element, applies an electrical current pulse to the igniting element when the trigger assembly is operated in a firing mode, the pulse having a duration which causes the igniting element to ignite propellant dispensed into the combustion chamber.
