Blue Sea 6006, 6007, 6008, 5510e & 5511e Battery Switch Diagram Guide

Battery switches may look similar from the front yet control different electrical paths. Blue Sea's m-Series 6006, 6007 and 6008 are single-circuit or battery-selection switches. The larger e-Series 5510e and 5511e operate two separate circuits, but only the 5511e includes a manual COMBINE BATTERIES position.

Before ordering or installing

A 6008 three-position selector is not a substitute for a 6007 four-position switch if you need to combine both banks. A 5510e does not add a combine position; the 5511e does. The 5511e is also not intended for switching one positive and one negative conductor because its combine setting would connect those circuits. Confirm battery voltage, operating load, starter current, cable size, terminal clearance and mounting space against the exact maker instructions. Do not turn a battery switch OFF while the engine is running.
