Hi Everyone, I have a hobby related question. I have used standard light dimmer switches on the front end of step down transformers to run my Lionel train. This has worked quite well when I set the train up for Christmas and run it all around the living room; one train on one power circuit. Now I've decided to run larger a larger set up with multiple trains and multiple power zones. It would be nice, and cost effective, to put dimmer switches on the 24 VAC side of the transformer. The standard dimmers don't work at this reduced voltage. What do I need to change on the 120VAC dimmer switch to have it work at 24 VAC?
