Upgrade your vessel or vehicle´s power management system with the BLUE SEA SYSTEMS ML Bistable Battery Switch Module 12V . Engineered for superior performance and safety in demanding environments, this heavy-duty remote battery switch provides unparalleled control and reliability for managing high-amperage 12V DC systems. It is the perfect solution for remotely switching large battery banks, engine starting circuits, inverters, and other high-load equipment without compromising on safety or power efficiency.

At its core is the advanced Solenoid Series ML technology. This switch features a fully sealed, bistable operation; the innovative magnetic latch does not draw any current in the ‘ON’ or ‘OFF’ state. It only draws a minimal amount of current for a fraction of a second when the switch state is changed, making it exceptionally energy-efficient and ideal for systems where battery conservation is critical. This "zero-draw" state prevents battery drain over time, a common issue with standard relays.

The reliability of this switch is second to none. The internal silver alloy contacts offer high reliability for switching live loads, ensuring a clean connection and disconnection cycle every time, even under significant electrical stress. This robust construction guarantees a long service life and consistent performance, giving you peace of mind that your power system is protected.

Safety is a paramount design feature. The switch is explosion proof and ignition protected, meeting stringent ISO 8846 and SAE J1171 standards. This allows for safe installation in marine engine compartments and other areas where gasoline fumes may be present. As one of the core modules in a modern electrical setup, its fully sealed IP66-rated case provides complete protection against dust ingress and powerful water jets, ensuring it can withstand the harshest marine and automotive conditions.

For ultimate convenience and failsafe operation, this module combines remote and manual control. The package includes an ML series Contura Switch for easy remote operation from your helm or control panel. In the event of a power loss to the control circuit, an intuitive manual override knob on the switch housing allows for direct operation, guaranteeing you always have control over your electrical system.

Main Features:

* Bistable Magnetic Latch Operation: Draws zero current in ON or OFF states, only during the switching action.
* Remote & Manual Control: Includes a Contura rocker switch for remote operation and features a manual override knob for failsafe control.
* High-Reliability Contacts: Silver alloy contacts ensure dependable switching of high-current live loads.
* Robust & Sealed Design: Fully sealed to IP66 standards for protection against water and dust.
* Certified Safety: Explosion-proof and ignition-protected for safe installation in potentially hazardous environments.
* LED Status Indication: Provides an output for a remote LED, clearly indicating the switch´s ON/OFF state.
* Heavy-Duty Application: Designed to manage high-amperage loads such as engine starting, windlasses, and large inverter banks.
