Abstract
A fault tolerant electromagnetic safety system for firearms comprises an electromagnetic actuator with movable rotating member operably interfaced with the firing mechanism. The actuator is controlled via a programmable microcontroller coupled to an electric power source onboard the firearm. A safety actuatable by a user operably interfaces with the actuator and is manually movable between actuated and standby positions. In a blocking position, the actuator engages and prevents the firing mechanism from moving to prevent discharging the firearm. The safety when in the standby position is configured to prevent the actuator from disengaging the firing mechanism. Upon the detecting movement of safety to the actuated position, the microcontroller moves the actuator to a non-blocking position allowing discharge of the firearm via a trigger pull. The safety when moving to the standby position may be configured to mechanically reset the actuator to the blocking position in event of an electronics failure.
