A compact battery switch that offers multiple installation options. Switches a single battery to a single load group. Blue Sea Systems m-Series battery switches are compact and waterproof and can be installed almost anywhere. The small footprint and three mounting options make installation easy. M-Series switches are ignition protected and can be located in the engine rooms of gasoline powered boats. The tactile texture of its face and removable knob makes operation in low light easier. Being removable, the knob adds a level of security and will prevent accidental power flow while servicing the electrical system. One piece tin-plated copper terminal studs are long enough to accept multiple cables and will accept the torque required to create a secure connection that minimizes resistance. For a small versatile battery switch that is easy to install and use, look no further than the m-Series from Blue Sea Systems.

Customers say
Customers find the battery isolator switch to be a solid, heavy-duty switch that works well as a cutoff switch and is easily installed with three installation methods. They consider it good value for money and appreciate its quality. The durability receives mixed feedback – while some say it will last 4-5 years, others report it breaking within minutes. The size also gets mixed reviews, with some praising its compact design while others find it too big for intended locations.

Best quality I have found
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.

Nice quality, works well.
Nice gear for 12 and 24VDC lithium systems.The Good:Easy install.Easy clean mounting.Clean, fast connect and disconnect when rotating.Runs reasonably cool (hardly over ambient temps).The Bad:I got nothing, theyâre great.ââââHowever⦠if you use them OVER the rated voltage use caution.Itâs not rated for ânominal 48VDCâ (>=52VDC in the Li world). That caused some issues with the mechanism over time.Never failed to make or break a connection. However, arc suppression is clearly visible during high current inrush and disconnect events.One switch began to run a bit warmer after dozen or two of those high current on/off actions. (Yes, I confirmed it was properly torqued with good lugs.)âââOverall:Great switch. They have operated flawlessly on my 12VDC and 24VDC circuits for well over a decade.Donât be complacent about the operating voltage rating! (Itâs easy to talk yourself into a ânominal 48Vâ system.)

Heavy duty disconnect in a small package… works great!
I installed this diconnect in my dad’s pontoon boat to disconnect the battery and stop parasitic draw on the battery when the boat sits. It worked like a charm. It is very durable with a heavy detent and a audible heavy click into place. The installation was straight forward. It looks nice and is smaller than competing product. It seems to be holding up well and is handling the outdoor weather well. The price is competitive on this one. You get a true marine grade disconnect at a good price.

Blue Sea Power Switch
I bought this to turn on/off my boat’s main battery. It works just as intended. It has breakaway access locations on all four sides, so it can accommodate multiple different setups. Blue Sea is a very reputable brand in marine electronics, so I trust it will work well and last. If I recall correctly, it doesn’t come with mounting fasteners.

De los mejores productos, tenemos un switch en 3 diferentes vehÃculos off road, nos funciona muy bien, ya que sus conectores de acero inoxidable y su capacidad de AMP es muy alta, aparte de ser resistentes al agua son resistentes al polvo.Lo único malo es que aquà en Amazon los costos de llavez extras y perillas son mas elevados, 3 dlls en Estados Unidos y aquà en esta misma pagina son 9 dlls.
