            Easy to install! Made boating so much easier

                I replaced my old Perko battery switch after 15 years of use with a new one. Fit the old holes, does the job, easy to connect, works great. Yeah!

                      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.
