摘要： Electrical apparatus including a housing enclosing a printed circuit board mounting a plurality of electrical components. The printed circuit board is detachably mounted on a pivotal support which permits rotation of the circuit board between various positions in the access opening to the housing. The support is a one piece plastic member which frictionally receives the printed circuit board in an elongated slot.

摘要： 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.
