Blue Sea 6005 m-Series (Mini) Battery Switch Single Circuit ON/OFF

The Blue Sea Systems 6005 m-Series (Mini) Battery Switch Single Circuit ON/OFF is a compact, marine-grade electrical control device designed to isolate and manage battery power to a single load group aboard boats. Built for ignition-protected safety on gasoline-powered vessels, this switch delivers the reliable power management that serious boaters and weekend fishermen depend on when operating electronics, bilge pumps, navigation systems, or auxiliary circuits in harsh saltwater environments.

The m-Series design prioritizes flexibility and durability. Its compact dimensions and lightweight profile (0.6 lbs) make it suitable for surface, front panel, or rear panel mounting, adapting to the electrical architecture of different hull designs. Multiple m-Series switches can be installed to manage several isolated circuits independently, or cross-connected for emergency parallel battery configuration—a critical feature when main power systems require backup. The ignition-protected design meets marine safety standards for gasoline-powered installations, reducing arc and spark risk in enclosed spaces where fuel vapors may be present.

This switch is ideal for anglers operating offshore or coastal vessels with multiple electrical loads, as well as cruisers and day-boaters managing auxiliary systems. Whether protecting a dedicated fishfinder circuit, controlling a secondary fuel pump, or isolating a thruster or winch system, the single-circuit architecture prevents accidental simultaneous load activation and simplifies troubleshooting. The isolating cover with snap-on sections provides intuitive operation and protects against accidental activation in rough seas or confined cabin spaces.
