The mount has 4 precut (sort of) holes for carling style switches. I wouldn't buy Rugged Ridge switches as they are expensive and frankly I don't like the look of them. The ARB compressor and locker both come with their own carling style switches. Follow ARBs directions because they basically make it a plug and play affair. For the other two switches, you could wire up whatever you want and would dictate how it's wired. Carling style switches can be picked up all sorts of places, and they even have some with no writing that looks just like the ARB ones if you're anal.
Personally, I currently have ARB compressor and locker switches going there in my '12 and two 3 position carling switches for lights. The 3 position is so I can run multiple things off one switch. For instance, one switch will be wired to my LED bar. One position is off, one is on, one is on only with high beam headlights activated. So if I'm on the road I can just dim my headlights as normal and it would also kill my LED bar. The other switch will be mounted to windshield mounted LEDs that are pointed to the side. Flip the switch one way, and it'll light up the left side, center is off, flip to right and it'll turn the right LED. I also have a small button on / off switch I plan to stick onto the side of the A pillar mount that when pushed will illuminate both side facing lights at the same time instead of one or the other.
