            Pros

            • Easy to install
            • Easy to use

            Cons

            • Cannot maintain
            • Cannot repair

            Best Uses

            • Boats

            Comments about Battery Switches:

            These switches are easy to install and use but if the contacts inside corrode, like they do when used in a boat, you cannot fix it. The have the back cover pop-riveted on so that you cannot access the contacts and spray them with anti corrosion spray.
