basic shut off switch that works.
I installed this on my small camper to shut off the batteries and prevent parasitic draws from draining the batteries. Easy to install and it works. Very simple, functional device. It should help my batteries last longer.

Beefy cut off switch.
It’s pretty large for my application but it’s the only thing rated high enough. I’m using this as a shut off for a winch on my truck which has a wireless remote. This prevents random remotes from being able to run my winch and also cuts power if I need to run through high water.

Good switch
Original battery switch (knob) on camper broke. This was like a direct replacement. Easy to wire, and even the screw holes lined up. Feels like it's well made and functions as it should. Would buy again.

Mechanically works perfectly. Fitment is 4/5
Its a nicely built product. Has held up great for months. Its rather smal and has a clean look and fit. Switch toggles very easily.My only complaint is the locking ring its so thin it makes it not tighten into place very securely. I would up adding a bead of silicone to the back to make sure it stays in place.

Excellent quality.
I am using this as a battery cutoff for a rear mounted winch that requires 0 - AWG cable. Big unit. Make sure you have room under the hood!
