### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    I almost bought the "other one" but so glad I didn't. This switch is great for my boat.
  

*by C***L on Reviewed in the United States on September 15, 2023*

First thing I did when I bought a boat is install a second battery because a dead battery on the water is both likely, and extremely problematic. Or worse.If you've shopped for marine battery switches you've seen the "other" brand. The big round, surface-mounted one. Then you see this one and think, "it's just so small" or "how does it mount to my boat?"I took the leap of faith and couldn't be more pleased with the results.My first consideration was accessibility. I didn't want the switch to be buried inside a compartment that would make access difficult while on the water. That way I could easily switch between batteries when we're fishing, using the downriggers and playing music, and back to when we're running the main engine. The smaller size and flush-mounting capability of the Blue Sea switch were definite advantages in that regard.My other consideration was the power handling capacity of the switch, especially because of its smaller size. A quick look at the published specs shows continuous, intermittent and cranking ratings of 350A, 600A, and 2,000A respectively. Way more than needed for my application. Another bonus is the "make before break" design that keeps all of my electronics alive as I switch between batteries. I never switch with the main engine running.I invested another 10 bucks in a hole saw and drilled a hole in the battery compartment facing the cockpit, then installed the switch flush to the carpeted front face. Bolted it in with new stainless hardware, terminated the batteries and not only is it functional, but it also looks great. No telling about long-term reliability at this point, but I'm glad I opted for the built-in look and accessibility of this switch.

    Battery switch

Product was purchased to take the place of a Perko Brand that was hard to turn. It worked perfect,  fit in the same space and much easier to turn the knob.
