As described - So far, so good!
Installed on a 2001 Chevy Silverado 1500 truck to solve a slow power leak problem. Easy install... and it has been working like a charm!

Reliable so far
This switch saved the trip in Seattle. I used it to replace a shutoff switch that went bad en route to Seattle. Thankfully we had ordered it and dropped at a locker. I was able to replace the faulty one and it's still working great!

Good, small disconnect switch.
This looks pretty solid and is smaller than others I have seen which is what I wanted. I haven't installed it you but it looks pretty straightforward. The price was good and the quality seems very good.

Substandard Materials
This was purchased for a trolling motor battery box and I thought the 100a switch would be suitable. The switch feels flimsy and not the robust feel you would expect to handle up to 100a. When tightening the nuts on the threaded terminal post the threads stripped on the post without excessive force used. Bad sign. I recommend spending a little more and getting a better quality shut-off switch.

Hole Size Explained
Looks and works great. I was working with 6 awg wire which the crimped eyelet connector fit great. I have a ressetable 40amp breaker between this shutoff and the battery. Good smooth switch action and I like the size for my Dash Panel on a deck boat. I wish vendors would show the hole cutout. I measured 1.125 (1-1/8") diameter on the threads and 1.0625 (1-1/16") on the flats. Flats are vertical so I am going for either a simple 1.1875 (1-3/16") hole or 3d printed plate that has a 1.1875 (1-3/16") diameter hole and 1.125 (1-1/8") on the flats.

Mounting problems
I think the switch will work okay, but the lock ring is out of tolerance, and pops off the switch threads when I try to tighten it. The switch will not stay tight in the panel, and spins when I turn it from on to off. I will attempt to fix it with some electrical tape on the threads, or some adhesive caulk, but it is annoying. When I go to the Nilight store, there is no customer support in sight.
