Abstract
A redundant actuation lock apparatus includes an interface, an electronic mechanism, and a manual mechanism. The interface manipulates lock bar(s) into a locked/unlocked position. The electronic mechanism includes an actuator and power drive. The actuator is disengageably coupled to and drives the interface. The power drive is coupled to and drives the actuator in response to a control signal. The manual mechanism includes a key input and an output. The key input receives and rotates with a mechanical key. The output disengageably couples to the interface and rotates with the mechanical key. The actuator is engaged with and the output is disengaged from the interface in an electronic mode, while the actuator is disengaged from and the output is engaged with the interface in a manual mode.
