## Description

Our master disconnect switch (Pollak 51-902EP) works on trucks, RVs, travel trailers, ATVs, marine vehicles, boats, and other machines that use a 12v battery. When you own these kinds of vehicles, you want to do everything you can to keep them in good condition to do their jobs with ease. If your vehicle battery is dead, then you won t get much done. The tools and certain steps of installation will depend on your specific vehicle and the battery placement, but the setup is an easy process overall. With 2 studs on the bottom of the switch, you will connect 1 to the battery and the other to the starter. Once in place, simply turn the lever and your battery and connected machinery will no longer have a connecting current. This will help prevent battery drain, electrical fires, and other potential issues that can occur when your battery is not in use. Another major issue that the battery switch can help you avoid is theft. If your battery and starter are not connected, then there will be no way to start your device. It is one of the best theft deterrent options out there, and you won t have to worry about losing keys or other small accessories. Our Pollak battery disconnect switch is made of heavy-duty, non-corrosive materials that are long-lasting and waterproof. With an easy to read faceplate, you will have no trouble remembering which setting is off and which is on . At Tornado Heavy Equipment, we take pride in our high-quality parts and our dedication to having informative and helpful customer service, which is something you don t get when working with larger companies. We also sell disconnect switches for construction equipment, cars, and other vehicles.
