Blue Sea 7718100 - ML-Series Solenoid Switch - Deutsch Connector - 12V

The Blue Sea 7718100 ML-Series Solenoid Switch with Deutsch Connector is engineered for applications requiring sustained control signals where a traditionally wired relay would draw excessive current. This 12V solenoid switch emulates the functionality of a normally open relay while consuming significantly less power, making it ideal for marine electrical systems, automotive auxiliary circuits, and industrial control applications where efficient power management is critical.

Built by Blue Sea Systems—a leader in marine and automotive electrical components—this solenoid switch features silver alloy contacts that deliver high reliability and minimal voltage drop across extended operational cycles. The Deutsch connector provides a weatherproof, corrosion-resistant interface suitable for harsh marine and outdoor environments, while the 12V design integrates seamlessly into standard automotive and marine electrical systems. The lower current draw compared to conventional relays reduces strain on battery systems and wiring, extending overall circuit lifespan and improving system efficiency.

This solenoid switch benefits equipment operators, marine electricians, and systems integrators who prioritize reliable remote switching with minimal power consumption. Real-world applications include engine start circuits, winch controls, auxiliary pump activation, and battery isolation systems where sustained control is necessary without the heat generation and battery drain of traditional relay-based solutions. Compatibility spans 12V DC systems commonly found in boats, RVs, trucks, and specialty vehicles—confirm your control signal voltage and Deutsch connector pinout before installation for optimal performance.
