2-Position Ignition Key Switch for Arctic Cat and Kawasaki Youth Quads
Arctic Cat 50 and 90 Utility, Alterra 90, Kawasaki KFX 50 and KFX 90, 2006-2023 - part number RMS110-105848
A brand new aftermarket two-position ignition key switch, supplied as a direct replacement for the original unit fitted to the Arctic Cat 50 and 90 Utility, the Alterra 90 and the closely related Kawasaki KFX 50 and KFX 90. It is a plug-and-play, direct-fit part: four wires into a single four-pin plug of the factory pattern, so it connects to the standard harness with no cutting, splicing or adaptation.
These small quads share a switch design across both brands, and it is a component that tends to give trouble long before the rest of the machine does. The barrel is mounted where mud and spray reach it, the quad gets washed down regularly, and the switch is handled every single time the machine is used. Water and grit find their way past the barrel into the contact block, and the wipers behind it lose their positive bite. The result is a quad that will not start until the key is wiggled, ignition that cuts out over bumps, or a key that turns freely and achieves nothing. Fitting a complete new switch cures the fault at source. Two keys and the connectors are supplied, and every unit is tested before shipment.

Frequently Asked Questions
Will it fit without modifying the wiring?
Yes. It is a plug-and-play, direct-fit replacement using the same four wires and the same single four-pin plug as the original switch, so it joins the standard harness as supplied. Nothing needs to be cut or spliced on the listed models.
What is included?
The two-position ignition key switch, two keys, and the connectors. Every unit is tested before it is shipped.
How do I know my old switch has failed?
The usual signs are a quad that will not start with the key turned on, an engine that cuts out when the switch or the loom is disturbed, a barrel that turns loosely with no clear click between off and on, and damp or corrosion inside the plug behind the switch. If the fault comes and goes when you move the switch, the switch is the likeliest cause rather than the wiring further down the machine.
Why is one switch listed for both Arctic Cat and Kawasaki machines?
The Arctic Cat 50 and 90 Utility and the Kawasaki KFX 50 and KFX 90 are closely related youth quads that share this switch design, which is why the same part carries Arctic Cat numbers 3305-998 and 3303-423 alongside Kawasaki numbers 27005-Y001 and 27005-Y002. Check the number on your original unit against that list before ordering.
