The control lever is the mechanism which starts landing gear extension and retraction. The lever is contained in a three-position module which is installed behind the pilot's center instrument panel. The lever moves in a guide which has three detents (UP, OFF, and DN) and is spring-loaded to stay in the detent that is set.
