ABSTRACT:
A slow motion actuating device has a housing with a first opening therein through which an output pin extends. The output pin is connected to a swing arm which is pivotally mounted in the housing and driven by a set of reduction gears. Stops are provided in the housing for limiting movement of the swing arm. An electric motor is mounted in driving relation with the gear set. The motor has a stall current which is low enough to allow the motor to be continuously stalled without damaging it. A printed circuit board is mounted in the housing with a tail portion extending through a second opening in the housing. The circuit board provides electrical connections to the motor and auxiliary contacts which can be opened and closed by a wiper mounted on the swing arm.
