Gen 2 Automatic Battery Switch

Intelligent, Hands-Free Battery Management for Modern Marine Systems

The Lewmar Gen 2 Automatic Battery Switch delivers reliable, automatic battery control designed for manual switching for today’s advanced windlass and onboard electrical systems. Engineered to remove the need for manual switching, it ensures your windlass receives power only when needed, improving safety, conserving battery life, and simplifying operation at the helm.

Smart Automatic Operation

The Gen 2 Automatic Battery Switch engages and disengages power to the windlass based on control-signal input. This eliminates the risk of leaving the windlass circuit live, reduces accidental operation, and helps protect wiring and components across the entire system.

Designed for Lewmar Windlass Systems

Optimised for seamless integration with Lewmar’s latest windlass models and control electronics, the switch provides dependable high-current handling while maintaining the fast response required for anchoring operations.

Marine-Grade Durability & Safety

Built with corrosion-resistant components and sealed against moisture, the switch withstands harsh marine environments and repeated high-load cycles. It enhances system safety by isolating windlass power when not in use, reducing electrical risk on board.

Easy Installation for Upgrade or New Builds

Compact and user-friendly, the Gen 2 switch installs cleanly in both new and existing electrical systems. It provides a professional, clutter-free solution that eliminates the need for manual breakers or mechanical switches at the helm.
