This switch controls the raising and lowering of the three-point hitch linkage. It is mounted on the lift arm assembly and sends a signal to the hydraulic control unit to initiate the movement. A faulty switch can cause the hitch to fail to respond to the operator's command or to drift unexpectedly. The manufacturer produces this component to match the original switch's contact geometry and mounting bracket, ensuring it seats correctly in the control housing without requiring wiring harness modifications.
