This light switch is an original component of the tractor's electrical system, responsible for controlling the lighting circuits. It is installed in the dashboard or control panel, where it completes the circuit between the battery and the headlamps or work lights. A failing switch may cause intermittent or complete loss of lighting, or the lights may remain on after the switch is released. The switch is manufactured to the original electrical contact geometry and housing dimensions, ensuring it seats correctly in the panel and maintains the proper contact pressure for reliable switching.
