Oh that's easy. This is what I have, total of 24 on my layout.
For DCC controlled switches, I would recommend Peco Insulfrogs with Peco switch machines (solenoid machines made for DCC).
The switches are high quality, last long. And the switch machines mount directly under the switch points. So there is no visible switch machine, or other device (like tortoise, that are mounted under the benchwork).
You dig a small 2"x2" hole in your foam, and fit the switch machines in there.
I like them because they are not visible.
Now you will need DCC accessory decoders also, they talk to your command station.
I have the NCE snap-it's. They are for DCC and solenoid switch machines.
