I am interested in controlling a super o switch with a relay. Is there a way to provide momenary power to the switch?
Ron, it sounds like you are working on the project that we discussed earlier.
The way that I handle that issue is to place an insulated track section away from the switch, and just run a single wire back to the non derailing feature of the direction that you want it to throw., NO RELAY REQUIRED.
The trick is choosing the correct location on the layout to place the insulated section, and let the train do the work. It sounds like you are well on your way, have fun!
