This replace the switch in my motorhome and it worked as it should. The build quality is good and it feels like a quality part.


I installed this switch on my 4 wheeler. It is a well made durable switch. I would buy this product again if the need presents itself. I am very happy with the switch.


I lost the key to my camper battery disconnect. I choose this product so I wouldn't have to keep track of another key. My disconnect is on the trailer. I wanted something that was Not Plastic, that can handle possible rocks and the weather (cold/sun).


Great price and good quality. Got this for my trailer battery shut off and it has not failed me yet.

I own an RV company and we use these kill switches on all custom installs. They're study and reliable.
