Abstract
Provided is a solenoid switch of a motor including a solenoid case, a solenoid having at least one control terminal for connection to at least one external control cable, two power terminals for connection to external power cables, two stationary serrated electrical contacts mounted within the solenoid case, where each serrated electrical contact is electrically connected to a corresponding one of the power terminals, two movable electrical contacts coupled to the solenoid and electrically connected to windings of the motor, where each movable electrical contact corresponds to one of the two serrated electrical contacts, and is movable by applied force of the solenoid. In response to a control signal received by the at least one control terminal, the solenoid is energized and moves the two movable electrical contacts to mate with the corresponding two serrated electrical contacts resulting in an electrical connection between the power cables and the motor windings.
