This switch is an electrical component used in the tractor's three-point hitch control circuit. It sends a signal to the hitch's control unit to raise or lower the implement. A failing switch can cause intermittent or no response from the hitch, preventing the implement from moving to the commanded position. The manufacturer produces this component to match the original switch's contact geometry and actuation force, ensuring it seats correctly in the dash panel and provides consistent electrical contact without requiring adapter harnesses.
