An aftermarket replacement ignition key switch for the Can-Am DS 250, built as a direct substitute for the original equipment unit. It is a two-position switch - off and on - with a four-wire tail 300 mm long and a single factory-pattern plug, so it is a plug-and-play, direct fit that connects to the standard harness with no cutting, splicing or adaptation.
Ignition switches on a youth and trail quad take a beating. The barrel sits out in the open where mud, grit and water reach it, the machine is regularly hosed down, and constant vibration works away at the contact block behind the key. The failures that follow are familiar to anyone who has owned one for a few seasons: the engine will not start until the key is wiggled, the ignition cuts out over bumps, or the key spins freely with no detent and nothing happens at all. Fitting a complete new switch restores clean, positive contact in one job instead of chasing an intermittent electrical fault through the loom. Two keys and the connectors are supplied, and every unit is tested before it is shipped.

Frequently Asked Questions
Will it fit without modifying my wiring?
Yes. It uses the same four-wire layout and the same single plug as the original switch, on a 300 mm lead, so it connects to the standard DS 250 harness as supplied. Nothing needs to be cut or spliced. Disconnect the battery before you start work to avoid shorting anything out.
What is included?
The two-position ignition key switch with its four-wire tail, two keys, and the connectors. Every unit is tested before it is shipped.
How do I know the old switch has failed?
Typical symptoms are a quad that will not crank with the key turned on, ignition that cuts out when the machine crosses rough ground or when the bars are moved, a key barrel that turns loosely with no clear detent, and corrosion or moisture visible in the plug behind the switch. If the fault appears and disappears as you move the switch or its connector, the switch itself is the most likely cause.
The DS 250 has been sold for many years - is this the right switch for mine?
This part covers the Can-Am DS 250 across the 2006 to 2023 span. The definitive check is the number on your original unit: if it reads S35010RCB000, this is the correct replacement. If your switch carries a different number, send it to us before ordering and we will confirm.
