How can I control turnouts with momentary switches?

A small panel next to a model railroad turnout has a toggle switch and two red and green LEDs

Q: I’m wondering how to control turnouts with momentary switches. Does a momentary SPDT toggle return to center off after it throws the switch machine? If so, will a light-emitting diode (LED) connected to the toggle stay on? — Ron Vowles A: It depends on how you wire it. A momentary single-pole double-throw (SPDT) toggle […]

For a DCC system to […]
