Abstract
An actuator unit for door locks or similar output devices includes two spaced linear actuators selectively operative respectively to lock or unlock the door through a common pivotally mounted link assembly. Such link assembly includes a lost motion connection to permit the energized actuator normally to cycle even if the door lock lever is being held to preclude movement thereof to the selected lock mode.
