ABSTRACT:
A controlled bi-directional motor is energized through a power switching arrangement of the type electrically operable in a manner to energize the motor for rotation in one direction and in another manner to energize the motor for rotation in the opposite direction. Circuitry including a single pole-single throw electrical switching device is responsive to the operation of the switching device electrically open to operate the power switching arrangment in the manner to energize the motor for rotation in a first direction and other circuitry also including the electrical switching device is responsive to the operation of the electrical switching device electrically closed to operate the power switching arrangment in the manner to energize the motor for rotation in the opposite direction.
