Good To Know

Q: Will this switch work with a key already in my tractor? A: No, this switch comes without a key; you will need to use a standard ignition key that fits the cylinder or replace the keyed cylinder separately.

Q: Does this switch handle both starting and accessory circuits? A: This switch is designed for basic ignition on/off function, typically used in older models where starter activation is separate. Verify your wiring diagram for exact terminal configuration.
