Great product. Great price

Easy to install! Made boating so much easier
Now I have all the switches in one place rather than trying to remember going to several different places.

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.

                    I have had serveral of these switches over the years. They last a long time if you do a little sealing work when installed. Simple bu effective design.
