Gary, I used single pole. I need 26 controllers, and three ways would have been a major expense. I thought if I did panel lights, I would just have one to show when the turnout was thrown. Btw, one of my ideas is to is pass the spring wire all the way through the switch handle and fasten it to the bracket on the bottom. I think this will increase the throw of the wire and increase the tension on the switch points. Of course, then I would have to use channel instead. The reason is, without the plastic pieces, the tension seems to be a little light, and when I installed that first one , I had to do a lot of ajusting to get it to work right.
And yes, I thought of coat hangers too, but I thought they would look to rinky-dink. After all, part of the hobby is the show.
