It's gotta be the headlight switch right?

I checked all the fuses with a voltmeter on each end. Everyone reads fine. I really thought it was a bad headlight switch but I've tried 3 different switches, 2 new and 1 old, and none work.

Since I can jump the plug connector for the headlight switch with a piece of wire and the lights turn on then I don't see what else it could be other than the switch...
