Thanks KD. I've tried the lamp next to the lever, and better yet, a lamp under the lever. It's OK but very often not convenient (like then the lever is on a tank) or clutters up the design.
I tried the toggle cell which I wasn't aware of. That's closer but I really don't want one or the other output on. It will do in a pinch but could raise havoc in tight builds. Just something that works like a lever but with a single light would be ideal.
