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.

### ⭐⭐⭐⭐⭐ Very Satisfied with this product !
*by G***R on February 22, 2025*

The switches are better than advertised, very solid , heavy duty & very well made . I especially like the separate on/ off plate & the index post to keep the switch from rotating! ! Arrived within 30 hours of placing the order at half the price, or less of NAPA ! Very satisfied !
