Have a 3w switch and am trying to locate it's use. Did a quick check of
some lights, outlets/split outlets. Lots more trial & error to cover.

Is this any indication of what configuration I am looking for?

- White on common (dark terminal and verified it's common with wires off
and a meter).
- Black (hot) on traveler - same physical side as common.
- Red on traveler (opposite side of common and other traveler).

Removing the wires from the switch and all open, black is hot, white & red
cold.

Thanks,
Al
