This is a brand new aftermarket three position ignition key switch for the Arctic Cat 250 and 300 utility and sport quads, supplied as a direct replacement to your original unit. It gives the standard three positions - off, on and accessories - through a 3-wire circuit on a single plug, and it comes complete with two keys and a connector, so you are not left cutting the old plug off the loom or having a key cut to match.
The ignition switch on these machines takes a hard life. It sits exposed on the handlebar cowl or the front fender where it gets rain, mud, jet-wash and vibration, and the barrel and the contacts inside eventually wear out. The usual result is a machine that will only start if you jiggle the key, or that cuts out over rough ground when the switch momentarily loses contact. Fitting is plug-and-play and direct fit, with a 530 mm wire tail giving ample length to reach the standard loom connection point. The quality exceeds the OEM equipment and all products are tested before shipping. It cross-references Arctic Cat OEM number 3303-850.

Frequently Asked Questions
Will this fit without modification?
Yes. It is plug-and-play and direct fit on the listed Arctic Cat models, with the same 3-wire, single-plug arrangement as the original and a 530 mm tail that reaches the standard loom connection. No cutting or splicing into the harness is required.
What is included?
You receive the ignition key switch unit, two keys and a connector. The pair of keys means you have a spare from the outset, and the supplied connector lets you renew the loom side if the original plug is corroded or has broken locking tabs.
How do I know the old switch has failed?
The classic symptoms are a quad that only powers up if you wiggle or push on the key, a key that turns but produces no dash lights and no crank, or an engine that cuts out over bumps as the worn contacts break connection. A key that has become sloppy in the barrel, or one that will no longer turn cleanly through all three positions, is telling you the switch is worn out rather than the wiring.
What does the third position do?
This is a three position switch: off, on and accessories. The accessories position feeds power to auxiliary circuits without bringing the ignition circuit live, which is useful for running lights or fitted accessories with the engine stopped. Bear in mind it draws from the battery, so do not leave it there for long periods.
