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 p...

Hi BFL13,
What matters most, in my opinion, is the contacting amperage. Mine are rated at 1000 amps, contacting, but only 100 amps continuous. As I use two in parallel that gets me to 200 amps continuous.
AC switches can be used but they have to be de-rated by about 90% on the voltage side. That means a switch with a rating of 125 volts is "right on the edge" for 12 volt use--because we often see 13.4 or higher. It would not matter when the circuit is closed--but it would matter when turning it "off" or "on"
