It is hard to mount directly to the battery. The problem is that side-mount battery cable connections are not flush on either the plug or receiving end, but the disconnect switch bar is flat, and that causes a problem. This is exacerbated in that both ends of the bar on the switch have threads. I was able to get it mounted. First I had to take the battery out to allow more room to work. Then I had to orient the switch bar 180 degrees off so that it was sticking out beyond the battery. I threaded the bolt through the bar and as far into the battery threads as I could. It was still loose. I then rotated the entire switch 180 degrees to tighten the switch to the battery. I put the battery back in and attached the cable, and I was done. It works fine. It just isn’t designed well, and none of the other options I looked at were designed correctly either. Some people drill out the threads, which would also work, but it really needs a design overhaul. Once installed, it works great.

Modifications required with drill for battery post as the hole is threaded and won’t tighten unless it’s fully threading into battery (my case anyway). Good concept but quality is questionable.

Works well with batteries having no post on top , just a top mount threaded bolt.

Got this for a beater truck that drains the battery for reasons that aren’t worth the effort of finding out… so a good switch is nice! Happily handles the power draw of the starter and the plow. The construction quality seems fine, no problems but not exactly industrial either. The knob makes for a nice indicator without exposed metal that could touch something like lever styles have. The lack of a any “click” when it’s switched is disappointing, though that doesnt affect the functionality
The issue I have is the installation, specifically the bolt holes. Both holes are threaded meaning you cant properly attach it to the battery without drilling out the threads on the battery side or the switch will be floating on the bolt rather than against the battery terminal. You could tighten them separately so that the switch is at a specific angle to the battery, but that makes installation a huge hassle and potentially impossible if the fuse box in the way. Both of those options are likely to cause the bolt to loosen and make a bad connection. Not a big deal if you know you need to drill one out, but if you don’t then it’s likely to come back to bite you. Would much rather see one hole unthreaded, or even both with a nut instead.

It worked well

I ordered this for a lawn mower with questionable wiring as an insurance policy against parasites/drains and winter storage. setup on a lawn mower battery worked well with only a little modification (battery bolt hole was too small). I needed to find a longer bolt to fit through both the battery post, the switch terminal, and fit a nut on the back. If you have a regular car/boat battery where you screw directly into the battery this should work very well.

Worked great. I have a parasitic draw somewhere in my new to me old 95 GMC. I just use it to go to the hardware store and make a run to the landfill. And I haven’t chased down the culprit yet but this battery off switch allows me to still use the truck every week or so without ruining the battery by having to recharge it everytime I want to use it. It’s a band aid fix but it will get me down the road for now
