This is another popular option. It is a Carling or ARB switch. They are available (obviously) from ARB (arbusa.com), Daystar (daystarweb.com). Digikey (digikey.com), and Carling (carlingtech.com), just to name a few. They are great switches and are sold to be waterproof (however, I have killed a couple while they were submerged). If you already have your switch panel setup for the smaller 1/2-inch-diameter shaft mount switch as shown above, you might have to redo your entire setup to get these put in. More of these switches on down the road though.
