same exact electrical prongs on the back. exact copy of original I took off. However, it is possible that Ski-Doo used a Canadian made part or something that was similar to this switch but had a Ski-Doo style key. Mine was more generic as was this replacement. This one did fit the wiring harness and had no splices for the mating female plug so I think it is original replacement part. I replaced mine because the snowmobile came with no key. Probably lost in the vast white wilderness of the North Pole.
