Abstract
A slotted rotor is fixed to a manual shaft operatable by using a shift lever. The slotted rotor is turnable in a restricted angle about the manual shaft. The rotor has a slot in arc segment a, slots in arc segment b, slots in arc segment c, slots in arc segment d, and slots in arc segment e that are arranged concentrically about the manual shaft, in that order starting from the manual shaft. As the rotor turns, the slots in arc segments d, e cause incremental pulses to be generated. Based on the number of pulses, a control unit detects deviation from the planned neutral position and establishes a correct neutral position. The position detecting apparatus and method make it easy for a worker to perform the neutral position alignment of a neutral start switch and to maintain the alignment after the switch has been mounted.
