I wanted this device to isolate the battery on my Classic American car, hence the need for a side post fitting. Bought another one,great product.

My husband has these on three of our vehicles. They work well and it’s so nice to have kill switch on the rigs we don’t drive often. These aren’t too big, they look fine and are easy to install.

This is a very good product as an isolation switch. It took me less than 5 minutes to install this device. The device doesn’t infers with anything around the battery. I am using this device on 2002 Chevy Blazer with 12 volts side post terminal. I will highly recommended this product for anyone who needs to isolate (shut off) the power supply from the battery to the rest of the vehicle.
