Abstract

An electronic trigger system with safety mechanism for firearms includes a trigger unit comprising an electromagnetic actuator operably coupled to the firing mechanism and a programmable trigger mechanism microcontroller. The actuator is changeable between a non-powered unactuated position and powered actuated firing position via pulling both an outer trigger and inner safety trigger of the trigger unit. The actuator is operably interfaced with a movable firing component of the firing mechanism operable to discharge the firearm. In a blocking position of the safety trigger, the safety trigger is configured to block outer trigger movement which prevents energizing and actuating the electromagnetic actuator thereby preventing the firearm from discharging. Conversely in an unblocking position, the safety trigger allows outer trigger movement sufficient to discharge the firearm by either energizing the actuator when a pre-selected trigger pull force threshold is applied or applying sufficient trigger force to manually trip the actuator.
