I think you are asking about what type electrical switch you need to control your turnouts. Depends on the type switch machine you use. Atlas' need a momentary contact, not sure about Peco or Tortoise,
Good luck,

Atlas switches are good for N scale. You will need to file the points for a tight fit though. I have had problems with the train derailing because the points were to thick at the ends.

Which switch should I use for n scale?
I plan to have a short wire run from the turnout to the edge of the layout so that the switch for the turnout control will be directly in front of the turnout.
