ABSTRACT:
A switch for controlling the current to an electric motor is disclosed. The switch includes first and second parts which are relatively rotatable about a first axis. The switch also includes contacts which are actuatable to permit electrical power to be applied to the motor in a direction depending upon the direction of relative rotation between the first and second parts. A portion of the contacts are carried by a rocker arm pivotally mounted against one of the parts with cooperating contacts mounted to the one part. Actuation of the contacts is controlled by an associated pivoting member located radially outward of the first axis and pivotable about a second axis, transversely to the first axis. The pivoting member carries a roller slidably mounted to an end thereof and resiliently biased against the rocker arm. The roller is of sufficient diameter to contact the rocker arm at two locations when the switch is in a neutral condition with all of the electrical contacts open. Relative rotation between the first and second parts causes the pivot member to pivot which, in turn, causes the rocker arm to pivot and close a set of contacts.
