Four Battery Switch Positions Explained

The Blue Sea Systems 6007 provides four manual battery selection positions:

OFF: Disconnects the switched electrical circuit from both connected batteries.

Battery 1: Connects the switched circuit to Battery 1.

Battery 2: Connects the switched circuit to Battery 2.

BOTH: Connects both battery banks to the switched circuit, electrically combining them while this position is selected.

The BOTH position should only be used when appropriate for your battery configuration and electrical system.

Corrosion-Resistant Marine Construction

The Blue Sea Systems m-Series Battery Switch (6007) features tin-plated copper terminal studs designed for excellent electrical conductivity and resistance to corrosion.

Its one-piece terminal stud design helps prevent loosening, while the protective rear cover helps shield electrical contacts from accidental contact.

IP66 Water-Resistant Design

With an IP66 rating, the Blue Sea Systems 6007 is designed to withstand dust exposure and powerful water jets under specified test conditions.

This protection makes it suitable for appropriate marine installations where moisture and spray are common. IP66 does not mean the switch is designed for continuous submersion.

Flexible Installation & Mounting

The m-Series 6007 supports three mounting configurations:

• Surface mounting
• Rear mounting
• Front-panel mounting

The protective terminal cover includes three snap-in side pieces to accommodate cable routing from different directions.

Always follow Blue Sea Systems installation instructions and use appropriately rated marine cables, terminals, and circuit protection.
