<p>CONTROL MECHANISM FOR REMOTELY MOUNTED MOTOR A control mechanism for a remotely mounted motor, such as an antenna rotator, is contained within a molded housing having a cover and base, and includes an indicator motor which rotates a switch assembly to a preselected location. The switch assembly is operated by a manually positionable dial having a knob accessible through an opening in the housing cover. The dial includes a cam surface which actuated the switch mechanism to control the direction of rotation of the motor and the repositioning of the switch to the manually selected direction. The tendency for the dial mechanism to rotate as the switch means is repositioned is resisted by means of friction pads positioned between the dial and the housing. The indicator motor is secured by a motor housing integrally molded in the housing base and a polyurethane pad cushions the motor. The motor housing includes side wall members and a cover attached thereto by an integrally molded hinge member on one side wall, and fastening means on the other side walls secures the cover and the motor within the housing. The housing cover includes integrally molded partial hinge members at one end thereof which cooperate with complementary partial hinge members molded into the base. Fastening means at the other end of the housing secures the cover to the base thus facilitating assembly.</p> |
