Coach Lighting The Easy Way...

[Super]

If they are only 'Momentary' Switches then I can't see how they would be good for coach lighting. Maybe best for them to control a momentary action on a Layout for example: Crossing gates come down and lights flash as a train rolls over a crossing and once passed, the gates go up and crossing lights go out. But with something like that there would have to be a magnet in each coach and engine to increase the 'momentary' time that the switch stays open or closed as the case may be.
