Abstract
A pivot position sensor sensing outboard motor trim includes a housing within which a pair of U-shaped movable contacts are secured in axially spaced relation on an operating rod which extends outwardly of the housing. The housing is attached by the motor. The end of the rod is interconnected by a flexible cable to a clamp coupler affixed to the tilt tube or shaft. The cable extends over the collar and wraps and unwraps thereon as the motor pivots to position the rod with respect to the motor. The fixed housing is provided with a chamber having a pair of wound linear resistor units secured in longitudinal recesses on opposite sides of the chamber and engaged by one of said contacts. At ninety degrees therefrom, a pair of limit contact strips are mounted in offset recesses on opposite sides of the chamber and connected by the other contact. At a preselected up-tilted position, the limit contacts separate from the strips and open the circuit therebetween to terminate up-trim drive.
