Standard Battery Switch For any vehicle that needs to use two batteries where one battery is used for starting the engine, while the other is used to power auxiliary loads. This is a common situation in trucks, boats, RVs, police and rescue vehicles, and in ambulances or fire equipment. A selector switch allows use of the first battery, the second battery, or both batteries simultaneously. This provides back-up starting power in an emergency. Features: These switches combine the functions of Battery Selector and Master Disconnect Switches to give four battery power options: Power cut off at the source Power On, Battery 2 Power On, Battery 1 Power On, both Batteries Battery selector switches provide a positive battery disconnect, which has many advantages: It gives a reliable shutdown of power during maintenance The version with the key protects against theft of the vehicle, when unattended It helps protect against electrical fires, when the vehicle is not in use, and minimizes battery drain Specifications: Rating: 500A intermittent, 310A continuous, 6-36V DC Electrical ratings on UL labels are conservative.
