    hmmmm... this "latching relay" bizzo is something I might investigate further. I could just add them on at a later stage, at the control panel, one for each turnout. Just have the "momentary on" buttons fire the turnout motor, as well as the relay. (hope there's enough "guts" in my CDU to do it).

    And the 'latching relay" for each turnout would maintain the constant current for the LEDs. hmmm... and could also be adapted for some sort of signalling, too I suppose. hmmmmm.....

    hmmmmm.... thinks a bit more......... And there's no little smiley thing for **pondering**. :)

    Hi Woodie,
    This would be my personal preference. If you want to use a separate
    relay, you would wire the two turnout coils in parallel with the two relay
    coils. You can use an Atlas Snap Relay. Using the DC return as common
    for the LED's saves one wire to the turnout.

    My take on this is that using the auxiliary switch on the point motor
    tells you the true condition of the turnout. The other control panel
    methods must infer the turnout position from which switch was last
    thrown or which button was last pushed.
