This is a brand new aftermarket 3-position ignition key switch, supplied as a direct replacement for the original unit. The switch has three positions - off, accessories and on - and comes complete with two keys. The ignition switch is the first component in the starting circuit: it feeds the ignition, the accessory circuit and the start signal, so when its internal contacts wear the symptoms can look like a much more expensive fault elsewhere in the electrical system.
Fitting is plug-and-play. The switch uses a single plug with four terminals and the original 40 mm exterior diameter barrel, so it drops into the factory dash aperture and connects to the existing loom without cutting, splicing or adapters. The 22 mm interior diameter and 65 mm overall length match the original unit. Every product shipped is tested before dispatch, and because a single switch design was carried across Arctic Cat, Yamaha and Polaris machines over many model years, the cross reference table below is the most reliable way to confirm fitment for your vehicle.

Frequently Asked Questions
Is any wiring modification needed?
No. The switch is plug-and-play and a direct fit. It uses one plug with four terminals, matching the original connector, and the 40 mm exterior diameter barrel drops into the standard dash aperture. No cutting, splicing or adapters are required.
What is included?
One 3-position ignition key switch and two keys. Every unit is tested before it is shipped.
How can I tell my old ignition switch has failed?
Typical symptoms are a dash that flickers or cuts out when the key is jiggled, accessories that only work in some key positions, a machine that will not crank even though the battery and relay are good, or a key that turns loosely without any detent between positions. Water ingress and vibration are the usual causes, and the fault often appears intermittently before the switch fails completely.
Will the supplied keys work with my other locks?
No. This is an aftermarket switch supplied with its own pair of keys, so it is not cut to your original key code. Any other lock on the machine that used the original key - such as a storage box or fuel cap - will still need the old key.
