Review: Rock-Solid, High-Quality Battery Switch You Can Trust - The Blue Sea Systems 6006 m-Series ON/OFF Battery Isolator Switch is exactly what you want in a critical electrical component: simple, reliable, and built to last. The build quality is outstanding — solid terminals, smooth but positive switching action, and materials that clearly hold up in a marine environment. Installation is straightforward, and the compact m-Series design makes it easy to fit even in tight battery compartments. What really stands out is the confidence it gives you. When it’s OFF, it’s truly OFF. When it’s ON, you know your system is connected without voltage drop or fuss. It handles high current loads effortlessly and stays cool under use. Typical Blue Sea attention to detail shows through: clear labeling, removable knob for safety, and excellent corrosion resistance. This is one of those products you install once and then never think about again — which is exactly what you want for a battery isolator. If you’re upgrading or replacing a battery switch, don’t hesitate. The 6006 is worth every penny and sets the standard for marine electrical hardware. Highly recommende
Review: Works perfectly for my application - This seems to be a high quality switch from a trusted brand. I use it to switch between two house batteries in my VW Westfalia Syncro Camper Van, or to combine both if needed. It also allows me to disconnect both batteries when needed, during wiring or electrical maintenance for example. I will say that it would have been nice to have a set of mounting bolts, however since it can be mounted in various configurations, I can see why they didn't include bolts since they'd have to supply several sets for the various mounting options. I mounted mine to a thin piece of wood in one of my cabinets initially with wood screws, but had to purchase some actual nuts/bolts/washers for a secure fit. Turning the knob to the various positions puts some serious torque on the unit, so a secure mounting job is required and the original wood screws in the pictures didn't last long. If you are mounting to a thicker panel, regular screws might work. Of course, you may want to mount it in one of the different configurations. Wiring is straight forward and I trust this will function for a very long time. Both batteries connect to the switch, which in turn powers a Blue Sea Systems ST Blade ATO/ATC Fuse Block, (https://amzn.to/2ZgpiPw - see picture) which in turn powers all the various and numerous 12v accessories in my van. This makes a great match for safely routing 12V throughout the van using two batteries. I'll update this review should the unit fail or give me problems in the future, but for now, I'm super happy. I could have spent a little less on a lesser known brand of switch, as there are many choices on desertcart, but Blue Sea Systems has a great reputation and I felt like it was worth a few extra bucks. I really don't want to burn down my van due to some cheap electrical switch!

### ⭐⭐⭐⭐⭐ Best quality I have found
*by J***I on September 2, 2025*

Great support and instructions available, built very well and exceeds my expectation of quality. Easy to wire and mount, just wish it came with mounting hardware like screws or nuts and bolts. Best value for my money with such high standards of quality in a switch that is used very frequently. Really makes my battery life last with the ability to use as a disconnect switch.
