Oil pressure switch

[Pal]

It might not be buggered it might just need to be cleaned. The float could be sticking or the wire going to the switch or a pin in a connector could be grounding.

On a side note there's some nice pictures of a R6 oil level gauge. The ring terminal is bolted to the engine so that is permanent ground. The float moves up and down on a shaft, when the float gets low enough it connects the ring terminal and the wire so the wire is grounded and your light comes on

Thanks mate, exactly the kind of answer I was hoping for.
Will check out at next oil change, which will be in about three weeks, as long as the snow holds off..
