Post #4 Good Advice:

........If I were you, though, I'd first try to remove the connector from that suspect switch to see if there's oil in it and in its wire loom. If so, you've found the source.

Post #2 is a common leak & good place to investigate if no oil in the oil pressure switch connector, quoted above.
