ABSTRACT:
An electrically energizable device of the type that may be selectively rotated through first and second angles of rotation in respective opposite directions in response to the electrical energization thereof in respective opposite senses supports and oscillates a disc member having two discrete circumferentially disposed electrically conductive areas separated by two discrete electrically insulating areas. This device is mounted upon the housing of an electrical motor in such a manner that the disc member is in axial alignment with the motor armature with a surface of each of the motor brushes being in sliding engagement with a surface of the disc member and in contact with a respective one of the electrically insulating areas when the disc member is in a neutral position. Electrical energization of the motor armature may be effected in respective opposite senses in response to the operation of the disc member through the first angle of rotation and through the second angle of rotation.
