No Full Beam, Dipped and Passing fine (CB500S)

After putting the fairing back on , I noticed the full beam isn't working though the dipped beam works as does the passing light (which uses the full beam bulb).

It's not the bulb since with multimeter probes in the plug, flicking the switch shows 0V at the plug but the passing beam button shows 12V.

What is the most likely culprit? I suspect the switch itself (though irritatingly, it was working fine on Friday) but what would be the best place to start trying to track down the problem?

""""I suspect the switch itself """"""
I agree.

It was the switch, didn't even need to disconnect it, just opened it up and sprayed some WD-40 in while flicking the switch.
