Got this for our camper. Was easy to install and works great. Good quality.

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.

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.

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.

Great on/off switch for our pontoon battery box. You will need a 2" hole-saw for the rear panel mounting method. I also used a bead of silicone adhesive around the hole ring to make sure water doesn't get in.Lastly, I ended up having to dremel off the ends of the 4 mounting screws, because they are too long and hit the battery - and stopped the battery lid from fully seating.Overall the switch works as it should. Just be aware you may have to modify your battery box and cut off the screws to make it fit properly for a rear-mount.

Works great and exactly as expected. You may need to use different screws depending on mounting location since the provided screws come with nuts to screw on the back. I went with self-tapping screws and right into the inner compartment of my boat where the batteries are located. Worked perfectly.

Great price and easy to install
