This magnetic switch is a component in the electrical system of the host tractor. It interrupts or completes the circuit that controls a specific function, such as a safety interlock or a power take-off engagement. The switch is installed in the cab or chassis harness and is actuated by a mechanical lever or a key. When the switch contacts wear or corrode, the circuit may fail to close, preventing the controlled function from activating. The manufacturer has matched the original switch's contact rating and mounting geometry so that it seats correctly in the panel and carries the same electrical load as the original component.
