Abstract
A Hall effect rotary switch includes a frame and a parallel rotor and stator mounted in the frame. There are a plurality of peripherally unequally spaced Hall effect sensing circuits mounted on the stator and a plurality of localized magnetic areas on the rotor. Movement of the magnetic areas adjacent the Hall effect sensing circuits provides output signals therefrom, which signals are used to determine the relative position of the rotor and stator. The localized magnetic areas on the rotor cooperate with detent portions of the stator to form a magnetic detent.
