Blue Sea Systems 6007 m-Series Mini Selector Battery Switch | 4-Position, 300A, Red

The Blue Sea Systems 6007 m-Series is a 4-position battery selector switch (Off/1/2/Both) built into a compact red housing sized for boats and RVs where panel space is tight. The combine position lets you draw from both battery banks at once, handy for an emergency engine start or keeping a radio powered when one bank is running low.

A make-before-break contact design switches between positions without an interruption in power, so connected electronics stay live during the change. It's rated for 300 amps at 32 volts, mounts on the surface, flush, or through a panel, and carries ignition protection for installation near gasoline engines.

• 4-position selector: Off, Battery 1, Battery 2, Both
• Combine position for emergency start or backup power draw
• Make-before-break contacts avoid power interruption when switching
• 300A / 32V rating for high-current battery bank switching
• Surface, flush, or rear panel mounting options
• Ignition-protected for use near gasoline engines

A solid upgrade for anyone running dual battery banks who wants simple, reliable control over which bank is doing the work.
