Good, solid battery isolation switch.

I bought this to prevent small current drains from killing the battery on my 25ft travel trailer while it was in storage. Much easier than disconnecting a battery lead each time!
The switch is a good, heavy duty design. I wanted to mount it so that I could shut off the battery power from the outside of the battery box. I didn't know if the supplied mounting screws would be long enough. Happily they are. I have a group 27 battery box with a group 24 battery. There was easily enough room to fit the switch inside the box and still fit the battery. The switch fit perfectly through a 2" hole and the supplied screws were long enough to secure it. I used 4 stainless steel washers from the local hardware store to complete the installation. A bead of silicon secured the back cover of the switch to make a nice, waterproof installation.
One safety note. If using this on a trailer, it should be in the "off" position ONLY when the trailer is being stored! If you attempt to tow the trailer with it "off" position, two bad things can happen:
1. Your tow vehicle can't charge your trailer battery.
2. In the event of a trailer separation, the trailer brakes will not come on.

Arrived quickly. Installed on side of the single plastic Battery Box (using negative wire). Install was fairly easy, biggest time was lining up drilling the holes into the plastic box. I also removed the battery from the box so it would be easier to put in the screws and tighten the provided nuts properly. Easy to attach the negative wire . You will need to purchase another cable to run from the cutoff switch the the actual battery. Had no issues, worked first time. Great to have this for storage purposes and just in general so you can entirely shut off the electrical and avoid battery drain. Remember to turn on when hooked up and traveling, otherwise trailer lights, electric brakes, and charging the battery while driving will not take place.

I just like this Ampper battery switch. I bought it as a gift for my brother who as cancer. (multiple Myolema) I would like to hook it inside his car as he has difficulties with the sensors in his car.(dead battery). I would have like to make it a DIY but would have require more instructions. Went on Google for a search on how to install but getting mixed infos. I know it should not be difficult such a hooking it to the -(negative wires to the Ampper battery switch then another cable from the battery switch to the -negative post. Attach the two cables with lugs to the Ampper battery switch inside the car through the fire wall. Make sure both the
Pos.+ -Neg. battery wires are unhooked before starting the project for safety reasons. Am I missing something???
I would appreciate installations infos. Tks.! Have a nice day!

+pos. and -Neg. car battery cable are off before carrying this work for safety measure

no more dead battery on my camper

my camper has a smoke and carbon monoxide detector in it that never turns off. it would kill my deep cycle battery in 3 days. I installed this cutoff switch easily right to the outside of my battery box and hooked up the leads on the inside. I works perfectly. No more dead batteries. and its easy click on and off.

good relaible and easy to install

I install this botton to shut the battery off when doing some electrical works. Sturdy. The only complain would be that the screws are a little too short. I would suggest to include a second set of screws maybe 1/4" longer for those who install it on thicker wall. Mine is installed on a 1/4" thick panel and I thinks the screws are holding with 2 threads.

Priced just right and solid built, just what I needed to disconnect my battery from my travel trailer with out removing a battery cable when I want the comfort of knowing that I do not have to worry about draining a battery when I am away from trailer but still allows my solar panel to keep charging battery

Me semble conforme à l’utilisation. Très utile pour couper le courant aux accessoires en aval du circuit. Permet de travailler en sécurité sans risque de court circuit. Les connecteurs sont très gros. Pas sûr qu’ils sont en inox par contre. Reçu beaucoup plus rapidement que prévue.
