Product Overview
This keyed switch restores normal key-controlled electrical positions on compatible tractors. Match the six-terminal arrangement and switch indexing because similar dashboards can use different wiring.
When a key jams, spins without engaging, loses accessory power, or only starts after being wiggled, worn contacts inside the ignition switch may be the fault.
