ABSTRACT:
A hand-held orbital polisher includes a housing, an electric motor and hand-operated motor control device mounted in the housing, and a pair of handles closely coupled to a housing to position an operator's thumbs adjacent the control device. The control device includes an electrical switch having a slidable actuator and a pair of thumb-actuated levers to selectively move the actuator into either of two on positions or into an off position. The levers are pivotably mounted to the housing, have a collar drivingly connected to the actuator, and a thumb pad at one end. The pivots can be defined at the other end of the levers and the collar at the center, or at the center of the lever and the collar at the other end of the lever. One or both of the user's thumbs can be used to apply a force with a force on one lever being transmitted simultaneously to the actuator and thereby against the other beam whereby to force the two levers in one or the other position, the operator's hand never having to leave the handles.
