ABSTRACT:
A shaft position digitizer has a jump transfer assembly coupling an input shaft to cams for moving magnet-carrying levers to provide discrete step-by-step operation and eliminate least significant digit ambiguity. A magnetically operated reed switch is aligned with the magnet carried by each lever such that the reed switches are opened and closed by movement of the levers to provide an electrical digital output representative of input shaft rotation.
