ABSTRACT:
A contact-free electrical pulse generator, that utilizes a Hall effect device and a permanent magnet to generate lines of flux and provides two stable output states when cooperating with a flux conducting cam having a stepped peripheral circumference mounted on a rotating shaft is disclosed. The flux conducting cam enhances the flux density imposed upon the Hall effect device when the high portion of the cam becomes proximate the Hall device. The concentrated flux lines flowing through the Hall device changes the state of the device in accordance with the preselected angular positions of the rotary shaft.
