I almost bought the "other one" but so glad I didn't. This switch is great for my boat.
Pattern Name: Switch Style: Selector 4 Pos.
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. ... show more

Well built
Pattern Name: Switch Style: Selector 4 Pos.
Liked ease of installation and the overall size. Added a second battery to my mule, needed switch to separate the batteries, has a winch and electric lift on a plow, rake and blade. Now has enough battery power. Great product! L. Jinks

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.

Works perfect
Pattern Name: Switch Style: Selector 4 Pos.
It showed up when they said it would. Easy straight forward set up. It allowed me separate my two batteries and keep one reserve to start my main motor if needed.

Built strong.

Didn't realize it doesn't come with mounting hardware.It does have plenty of room inside for multiple 4 gauge wires I give it 5 stars regardless of no mounting hardware.

Excellent buy

Our previous battery switch corroded. We replaced it with this one. Quick and easy to install. Works perfectly. Cheaper on Amazon than most local stores.

Awesome battery switch, It's Big!
Pattern Name: Switch Style: Selector 4 Pos.
Go for this switch you won't be disappointed! It looks great, is very well built and functions properly. There are 2 caveats: 1) This switch is very large, the face size is 3 5/8" - so if you are planning on the "flush mount" or "rear mount" option, you will need a smooth-cut 3 5/8 hole, which is a rare hole saw size, so you'll probably want to order one of those at the same time. 2) It doesn't come with mounting hardware. I used 1/4" marine grade nuts/bolts/washers. I did the flush mount option and I used 1 1/2" bolts which were a touch on the small side for flush-mounting. I would recommend 1/4 x 1 1/2" bolts for front mounting and 1/4 x 2" for flush-mounting. Upon installation and first use I was extremely happy. Jammed the stereo with sub-woofers for over 2 hours on the lake in position "2". Attempted to start the boat in position "2" - click-click. Switched to "1" and she popped right off! Exactly as intended! I have yet to be 100% sure that it recharged both batteries in 1+2 mode, but it really must. ... show more
