I want a pot with the switch, not a seperate switch. It must be double throw. I only need a single pole, but double would work. I can't find a 500k pot with a rotary switch that is double throw. I'd even take a push/pull switch that's double throw. I found a couple of sites that have them, but they don't mention the throws. I'm guessing they are single. StewMac has the one, but I don't get the on/on thing.
