Review: Good Solid Switch - I was looking for a battery cut off switch for my trailer that would be accessible on the outside of my battery box. I didn't want the style that had a removable key, and I wanted one that would be durable. I also didn't want to spend a small fortune on it. This one fit the ticket. It was a little larger than I thought it would be, and I had to change the side of my battery box that I had originally planned on having it attached. It protrudes inside the box by several inches, and it would have hit my battery. I like this switch. It has a nice solid construction, metal instead of plastic. There is a definitive "click" when you switch it on. Now I don't have any parasitic drain on the batteries while in storage, and I can turn off the power even if my battery box is locked. The threaded shank of the switch is flat on two sides so you can get a wrench on it. I decided to drill the hole for it slightly smaller than the shank and then use a file to shape the opening to match the shank. This way when you tighten the nuts down, the switch won't rotate in the opening. I used a dab of RTV silicone behind the outside plate to prevent water getting in the box. I have had this setup for a year now and have had no problems with the switch, or water getting in the box.
Review: Great switch! - I shopped several other brands for a good HD Battery disconnect for my Miata. I mounted this right under the rear hatch lock which already had a factory hole. I only had to enlarge it a little and it installed easily, in less than 15 minutes. Part is heavy duty and so far works perfectly. Now I'm legit at the track and no need to fumble with disconnecting the battery which is often.

### ⭐⭐⭐⭐⭐ Big n Beefy, great customer support momentary capacity of 1000 amps.
*by D***X on March 15, 2021*

So I installed one of these in a buddy's jeep previously, its still hanging in there after months of on / off switches. This time I bought 2 for myself to install on a 96 F350 4x4 PSD box truck. I spent a bit of time fabricating 2 mounts so I can secure the switches near the radiator frame mount down near battery trays, Ideally you want the switches as close to source as possible ( but I have put disconnect switches in cabin just requires alot of expensive heavy gage cable. The pax side requires a bit of effort as two - 2/0 cables go from big OEM positive lug to starter and relay as well as the 2/0 series cable from drivers side (2 batts on a diesel, your application may differ). Yes the switch body is not indexed, if you install the switch with out securing the large faceplate it has a tendency to turn on you, its easily rectified by drilling a small screw thru faceplate (I used a self taper and then just cut off excess). This switch is beefy but it needs to be to handle cranking current an email with Andy at legacy auto (supplier) stated constant current at 180 but momentary at over 1000 amps. Another buddy has a 2001 PSD, he paid some guy to do his using some other brand switch and was charged over 500 dollars, I dont have that kind of cash and I prefer to do things myself.
