Blue Sea 5510E e-Series Dual Circuit Switch

Description

The Blue Sea 5510E e-Series Dual Circuit Battery Switch allows two independent battery circuits to be switched together with one control while keeping the circuits electrically isolated from each other. This simplifies normal battery operation on boats with separate engine and house systems without permanently combining the two banks.

The switch is ignition protected for appropriate gasoline-powered boat installations and meets ABYC requirements for marine battery switches. Tin-plated copper studs provide strong conductivity and corrosion resistance, while the extended stud length gives installers room for multiple cable terminals when the electrical layout requires it.

Tactile textures on the knob make switch position easier to identify by feel, which is useful in dark battery compartments or confined installations. The housing supports both surface and rear-panel mounting for installation flexibility. For dual-circuit battery systems that need simple coordinated On/Off control while maintaining bank isolation, the 5510E provides a rugged e-Series solution.
