  • Patent number: 8113103
    Abstract: Trigger apparatus for use with firearms are described herein. An example electronic trigger apparatus described herein includes a first actuation drive to move an actuation member between an initial position and an operating position at which the actuating member is to activate a trigger lever of the firearm to discharge the firearm. A clutch is movable between a first position to operatively couple the first actuation drive to the actuation member and a second position to releasably couple the first actuation drive from the actuation member. A second actuation drive is operatively coupled to the actuation member and biases the actuation member to the initial position when the first actuation drive is releasably coupled from the actuating member via the clutch.
