Oil pressure switch issue...

So it's done it since I've owned the truck, but anyway...Turn the key on: Oil pressure goes to about 40-45psi on the gauge. "Wait a minute.. I haven't even started it.."Stays there, too, after I start it, and drive it. It stays put there, as long as the key is on.. If I unplug the Oil Pressure Switch harness, it goes to zero, so something tells me it's the actual pressure switch?... At the nice price range of $180 (Rock Auto), to $212 :moon: at Advance Auto Parts; Auto Zone wants $193 for it.. :nono:Is there something you guys may know about that could be causing this? I mean, something like the 'low oil pressure) TSB, but opposite, obviously.. :)Thanks.
