Beschreibung
Zusammenfassung:	An adjustable limit switch mechanism for controlling the operation of an electric motor of a garage door opener over a selected range of movement including a motor driven threaded shaft supporting at least one switch actuator which is adjustably positionable and restrained from rotary movement while being axially translated by rotation of the shaft. A limit switch is mounted adjacent the threaded shaft so as to be actuated as the switch actuator is translated axially on the shaft.
