Noted today that the oil pressure light on my TBS did not come on with the ignition.
I did the usual checks and determined that the switch is faulty (not the bulb).

Does anyone know if there is a generic replacement for this switch that may be more easily available and cheaper than the OEM item?

Well the damn thing started working again and then it stopped again and then it started working again.

I think I will give it an oil change over the weekend and see if it might flush some gunk out of it.

I'd think most items from an auto parts store would work so long as the thread size matches up. I'm guessing, but I doubt there's much variation in the pressure these things switch at for most engines. Surely most engines' shell type bearings (& that's most engines) require much the same pressure & the oil pressure warning switch isn't likely to be a very nuanced device?

Tried all the local auto parts/electrical shops for an oil pressure sender unit after mine started displaying the same symtoms. Not one of them could match the thread.

A bit tangential to the topic....

Is an oil pressure switch really useful? With the quality of modern engineering I've wondered if these switches have much value these days? I tend to think that an engine will show symptoms of wear long before the oil pressure system packs up. A few weeks ago, in very heavy rain, my warning light came on. Throttled off & looked as best I could to see if I had a trail of oil behind - even tho' I'm sure I'd feel a major oil loss hitting the rear wheel. Everything seemed normal otherwise, so I carried on. When things dried out a bit, the light went back out. (I checked the wire route over the back of the engine, seemed ok.)

What do others think on this?

Mike,
you are probably correct in what you say about showing some signs prior, but these are called idiot lights for a reason.
Many people would not know a sign if you hit them over the head with it.

After being in a heavy rain, my oil light came on and stayed on. I checked the level, couldn't hear any new noises, so I rode it. Bought a new switch, but the old one started working after it dried for a few days. I thought about making an adapter to fit a generic switch, but the OEM wasn't quite THAT expensive.
