I'm starting phase one of what will eventually be a fairly complex Rokuhan Z-scale non-DCC (for now) layout that will feature 26 or so turnouts. Obviously, that's a lot of their controllers to line up next to the throttle (even if there's enough juice coming out of the throttle to power them all) so my plan is to use a separate power supply and build a control panel using DPDT Momentary On Toggle or Rocker Switches. However, I'd really like to include some sort of LED indicator that will stay on to show if the turnout is open or closed, but with the switches being only momentary on they're not going to do the job by themselves. Does anyone have a solution? A link to a product, a circuit I could build or a bit of magic? I'd even consider a simple to use computer based system if someone could recommend one that's compatible with Rokuhan.
