This switch is mounted in the fender of the host tractor and controls an electrical circuit, typically for lighting, auxiliary power, or implement control. It is a direct-acting, push-button or toggle mechanism that opens or closes the circuit when actuated by the operator. The switch is an original component, meaning its contact geometry and housing dimensions match the factory cutout and wiring harness connector, so no adapter or bracket is needed during installation. A failed switch will cause the controlled function to remain off or fail to disengage, depending on the circuit design.
