ABSTRACT:
An actuating device for automatically controlling the position of a movably mounted vehicle mirror comprises a motor controlled by switches for selectively actuating the motor in response to angular displacement of a trailer with respect to the vehicle. The switches are actuated in response to movement of the trailer and responsively close a circuit connecting a power source to the motor. Preferably, the switching means can include means for disconnecting the power source after a predetermined rotation of the motor in order to avoid excess energy use. Preferably, the disconnecting means comprises a plurality of switches arranged to contact lobes of a rotating cam at predetermined rotational positions of the cam. The cam can be concentrically secured to the rotor shaft or can be connected to the rotor shaft by a lever mechanism in order to form a crank which translates the rotor movement to linear displacement on a mirror positioning member.
