SURFACE MOUNT IN LINE BATTERY ISOLATOR  Battery Selector/Master Disconnect 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 and 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.

Either or both batteries can be selected for energizing. 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.
