Abstract
A Hall effect rotary switch includes a stator and a rotor. The stator mounts a row of spaced Hall effect sensing circuits. There are magnetic means for causing activation of the sensing circuits, with the rotor selectively positioning said magnetic means adjacent said Hall effect sensing circuits to provide coded outputs therefrom at different positions of the rotor.
