3-Position Ignition Key Switch for Kawasaki Mule
KAF 300, 400, 540, 620 and KAF 950 Mule, 1990-2023 - part number RMS110-105004
An aftermarket three-position ignition key switch built as a direct replacement for the original unit fitted across the Kawasaki Mule utility range. It is a plug-and-play part: the six-wire tail carries a single factory-pattern plug, and the connectors are supplied with the switch, so it goes onto the standard harness without cutting, splicing or any adaptation of the loom.
The switch offers three positions - off, on, and a spring-return start - so a single barrel handles the ignition feed and the starter signal. On a Mule that spends its life on a farm, a site or a smallholding, this is one of the components that wears out first. Dust and grit find their way into the barrel, water and pressure washing reach the contact block behind it, and constant vibration loosens the internal wipers. What the owner notices is a machine that will not crank until the key is jiggled, an engine that dies as the key springs back from start, or a barrel that spins freely with nothing happening at all. Fitting a complete new switch cures all of those at once and removes the need to chase an intermittent fault around the rest of the wiring. Two keys are supplied, and every unit is tested before it is shipped.

Frequently Asked Questions
Will it fit without modifying the wiring?
Yes. This is a direct-fit, plug-and-play replacement. It uses the same six-wire arrangement and the same single plug as the original Kawasaki switch, and the connectors are supplied, so nothing has to be cut or spliced on the listed models.
What is in the box?
The three-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 classic signs are a Mule that will not crank while the key is held at start, an engine that stops the instant the key springs back to on, ignition that drops out when the loom or the switch is disturbed, and a barrel that turns loosely without a clear detent between positions. Corrosion or green deposits in the connector behind the switch point the same way. If moving the switch or its plug makes the fault come and go, the switch itself is the most likely culprit.
The Mule range spans thirty years - is one switch really right for all of them?
This part covers the KAF 300, 400, 540, 620 and 950 Mule across a 1990 to 2023 span, but Kawasaki used more than one switch design over that period. The safest check is the number on your original unit: if it reads 27005-0011, 27005-1191 or 27005-1146, this is the correct replacement. If it reads something else, contact us with the number before ordering.
