Turnout switches

Model Railroader General Discussion (Model Railroader)

I have 3 questions regarding switches for Atlas under the table machines?

  1. Can I use toggle switches to control them? If so which kind?

  2. Can I wire LED’s to the switch so I can visually see which lead I am on at the turnout?

  3. Can I use 1 switch for 2 turnouts, as in the case of a a slip between two main lines?

Thank you all for your help.

  1. Can I use toggle switches to control them? If so which kind?

Yes, but they have to be momentary contact types. You want a single-pole, double-throw momentary (SPDT-MOM) toggle. The toggle handle will spring back to the center position when released, so the switch machine is only energized while you’re holding the toggle over.

  1. Can I wire LED’s to the switch so I can visually see which lead I am on at the turnout?

Not without providing additional switching contacts, for example by using the Atlas Snap Relay along with the switch machine. See my book, “Easy Model Railroad Wiring,” page 99, figure 9-21.

  1. Can I use 1 switch for 2 turnouts, as in the case of a a slip between two main lines?

Yes, as long as the power supply has enough capacity to operate two switch machines simultaneously.

Good luck,

Thanks for your advice. I also went out and purchased your book last night. It looks as if many of my future questions will be answered there as well.
