    Abstract: A manual switch remote controller is adapted for use with a power switch machine to electrically and selectively move switch points of a track switch between a normal position and a reverse position from a remote location in the field. In one preferred embodiment, the manual switch remote controller includes a first switch for selectively connecting and disconnecting a first source of DC operating power from first and second input terminals to first and second output terminals which are coupled to respective first and second input operating terminals of a biased-neutral controller. A second switch is used for selectively connecting and disconnecting a second source of DC controlling power from third and fourth input terminals to third and fourth output terminals which are coupled to respective third and fourth input control terminals of the biased-neutral controller.
