Pete. I looked all over that site for a phone number and could not find one. I will look again. Found the instructions. The backing opens up and there they are. Can't belive I did not notice that. The only way to test it properly is to put it in my layout, meaning I will have a lot of track to remove. I only hooked up one side of the switch, for it to work right track power has to be applied to both tracks and on both ends. Thanks
Chuck 🙂
