Same switch you might see being sold for a few bucks more. Came very quickly. The only thing to know is that this basic switch is rated for 275 Amps. If you're running a massive 3000 Watt inverter you'll need the Blue Sea 9003e ON-OFF Battery Switch rated to 350 Amps. Which means using 4/0 cable instead of 2/0 cable. If you can get away with 2/0 (or smaller) then this switch is definitely all you need. Seems heavy duty, solid.
