Abstract

An electronic trigger rotary latch includes a trigger cutout, a controller in electrical communication with a plug receiver. Springs are engaged to the latch and trigger pawls. A gear motor having an actuator engages a surface of the trigger pawl. A handle includes a striker bolt and an electrical plug. In an unlatched configuration the striker bolt is separated from the latch pawl, an electrical circuit is open, the latch pawl spring has reduced compression, the trigger pawl spring has increased compression, and the trigger tip is engaged to a latch tab. The actuator has moved the lower leg in the trigger cutout. In the latched configuration, the striker bolt is held by the latch pawl, an electrical circuit is closed, the trigger tip is engaged to the latch shoulder, and the trigger leg has been moved in the trigger cutout in an opposite direction.
