I originally used a rotary switch. One thing I did do was not run track power through the switch itself. I used the switch to turn off power relays. I like 14 gauge wires for feeders and thought the bundle of heavier wires would put a lot of strain on the rotary switches terminals. While I liked the function of the switch. I found you needed an indicator light to know what track you dialed up.
When I added DCS I added a toggle switch that had to be thrown after you dialed up the right track. I did this after finding out as you rotated the switch the brief power applied to each track would start the DCS engine up in conventional as it would miss the watchdog signal.
My hopefully final rendition is all toggle switches lined up in order for each track they represent.
