ABSTRACT:
A rotation sensor provides a control with an indication of shaft position. The sensor utilizes a magnetic connection between a cam follower and a transducer. The magnetic connection eliminates problems in the prior art such as degradation due to wear and corrosion. In particular, a rotating shaft carries a cam. The cam drives a cam follower. As the cam follower moves, a magnet moves. The transducer can sense movement of this magnet. In preferred embodiments, the cam follower is driven to pivot and the magnet is mounted on the pivot point of the cam follower. The present invention is disclosed for use in motorcycle throttle handles, accelerator pedals, brake pedals, and detecting shaft position for valve timing.
