Battery Switch for Marine Boat RV ATV Vehicle 6V 12V 48V 60V Battery Disconnect Master Isolator Switches Heavy Duty Waterproof Cut Off Shut Off Disconnect

No it’s not a Blue Sea or Perko but it does its job well for my application. I wanted to add a 12 volt dc light over my sump pit, using the sump pump battery. I have the sump backup pump and light wired through this switch. Now for the boat I would recommend paying for the Blue Sea or Perko battery switch. They are simply built better, you do get what you pay for here. The terminals are close enough together that it would be hard to route number fours and heavier gauge wires to this switch. You would have route them from at least two different directions, if not three, as this switch is considerably smaller than the other brands I have mentioned. 5 Stars for this application, for a boat where you need reliability and such, just buy a BlueSea or Perko switch.

I installed this switch as a power disconnect for the DC side of a travel trailer. The lugs are robust and the switch seems to be substantial. The quarter turn from on to off is very positive. The mounting screws were included, which made installation a breeze.

Installed in Cat skid steer to isolate battery + terminal. Working well. Need to make sure cable terminals stay separated with shrink material or liquid insulation. Well made.May require making a mounting plate and drilling some holes to firmly attach it to vehicle frame.

Although the unit came in an OpenBox its simplicity suggested that it would not have been damaged by others prior to me. I was right. The switch was installed with little effort and is a great addition to my electrical system. Sure..recommended.

Planned a 2 battery switching system for quite some time for obvious reasons. These switches can get terribly expensive. When I found this price it was time to complete the project. I didn't mount it where it would be in the weather. Just seemed like a bad idea. I can see where a dashboard mount would be convenient but I mounted it inside the battery covers under and enclosure so weather will not an issue. Lift the lid switch the battery on, no big deal. It is a heavy A/B/A+B/ OFF rotary switch. The connection bolts appear to be stainless steel so corrosion shouldn't be an issue, I coat them with dielectric grease anyway. This is the same heavy duty switch sold in the marine stores for way more money.

Switch did not come apart like some illustrations. Had to mount as one piece. But it works and is a good fit for my project.

The switch is exactly what I wanted. I was replacing an existing where the prior switch would not connect to two batteries. The hardware supplied was good stainless machine screws. I used 5/16 ring connectors on the battery cables which had plenty of room on the lugs of the switch.

Does NOT allow for normal electrical pass through. Too much resistance. OEM warning buzzer wouldn't shut off until I disconnected switch and hooked straight to battery. Here is the complete story: I purchased this switch a few weeks ago with excitement to have two batteries; I was tired of dragging a jumper pack. Started great and on the lake we went, with high hopes to get some boating in on July 4, 2023 (Independence Day). Warning buzzer was screaming in idle, which made helping three people on a flipped wave runner frustrating. Ran the boat for almost an hour before I shut the boat off in the middle of Utah lake, bad idea. Boat ignition switch was completely useless (dead completely). I directly connected to the battery, bypassing this switch, and it started right up. Don't forget your tools like I did!! Wife and daughter are already timid to be on a lake and this didn't help. Go back to the old reliable, extra battery (not connected) or jumper pack.
