Battery Disconnect Switch Master,12V-48V Waterproof Battery Shut Off Switch,Heavy Duty Battery Isolator Switch,275Amps High Current for Car Marine Boat RV Vehicles(On/Off)

with this what you see is actualy less than hat you get, when i recieved mine i was surprised, is larger than i pictured, as you turn the knob thru its positions, it is a solid motion and "locks in" its not all wishy washy its a positive "click" into position...... the lugs where the cables are connected are like 3/8" bolts that are solid enough to put a wrench on and tighten properly without breaking...... it also has a cover plate to cover where the cable connections were made,,,,, theres actualy nothing i could say bad about them other than i wish they had been giving them away when i bought mine :)

This was a great add on to my camper. Had an in line fuse I had to keep pulling when not needed, but this is as simple as a turn. Would buy again.

Battery on battery off.

Make sure you get some good crimp on eye termenals so you get a good connection. I use this to cut off on my rv batteries hooked inline on my ground wire

So far so good, nice and also wise to have. Functions as intended.

I use these a lot on boats and other projects. Never had a problem.

worked well for my 3000 watt razor retrofit

I added this to my RV to prevent the battery from dying during long term storage. It looks well made and functions as described. This is a very good product.
