That can't be good. Certainly sounds like more than a pressure switch. Other than that it's gonna take some diagnosis.

I think your engine is damaged. If your oil pressure dropped, then that means you lost lubrication on your crankshaft and stuff. Oil is fed under pressure into the space between the con rod bearings and the crank. Not to mention other places. But anyway, lost oil pressure means metal to metal contact between parts instead of a nice oil film in between. Probably got some engine damage. How long from when oil pressure light came on till you turned it off?
