Especially for use with a door panel hinged on a frame for relative swinging movement is a device for so swinging the panel relative to the frame, the swinging device being responsive to a switch. An arm journalled on an eccentric hub rotatable with the door frame is movable in one direction against a stop and in the other direction against a switch that controls the operation of the panel swinging device, in this way affording an easy and proper control of power door operation.
