Abstract
A control unit, adapted to control a reversible, variable-speed electrical motor includes a control lever protruding through a U-shaped slot in a housing. Movement of the lever from one side to the other of the U-shaped slot controls the direction of rotation of the motor, and its position along a side of a slot determines the speed of rotation. The control lever is mounted to a pivotally mounted support member, which carries a linear potentiometer operated by the control lever, and includes a protruding portion which carries a toggle switch. The handle of the toggle switch is substantially restrained from motion, so that the switch is actuated to reverse the motor when the control lever is moved from one side of the U-shaped slot to the other.
