Recs for Solar Cut Off Switch?

Looking for help finding some sort of cut off switch that I can mount on the wall inside my coach next to where the charge controller is currently mounted.

Side note: I'm pretty much hemmed into putting the cut off switch next to the charge controller due to the way the previous owner wired the array into the coach.

Trying to find anything that isn't big &/or big & ugly has proven to be an exercise in futility.

Thanks in advance!
