Abstract
An apparatus for signaling rotation of a winch in which a rotating gear internal in the winch turns an optical disc with alternating segments of distinguishing features. The disc is then in turn read by an optical sensor that can generate a pulsed output signal based on the travel of the alternating segments on the disc. The output signal of the optical sensor is then conditioned to drive a solenoid that is placed in a control lever of the winch. The optical disc and the optical sensor are part of a self-contained unit which can be inserted internally into the winch housing.
