Blue Sea 7718 - ML-Series Solenoid Switch - Stripped Wire - 12V

The Blue Sea 7718 ML-Series Solenoid Switch with stripped wire terminals is purpose-built for marine, automotive, and industrial applications requiring reliable sustained control signals at 12 volts. This switch replaces traditional relay configurations in scenarios where lower current draw and simplified installation are priorities. Ideal for battery isolators, engine start circuits, and remote switching systems, the 7718 delivers consistent performance in demanding environments where durability and dependability are non-negotiable.

Silver alloy contacts provide superior electrical conductivity and extended contact life, resisting corrosion and arcing common in harsh salt-air or high-vibration settings. The solenoid design emulates a normally open relay while consuming significantly less current than comparable mechanical alternatives, reducing strain on battery systems and control circuits. Stripped wire terminals allow direct connection to custom harnesses or panel installations, eliminating the need for proprietary connectors and enabling flexible integration into existing electrical architectures.

Marine professionals, RV builders, and automotive technicians favor the Blue Sea 7718 for permanent installations where space and weight constraints demand efficient, compact switching solutions. Its 12-volt rating makes it compatible with standard automotive and marine 12V DC systems, including dual-battery setups and auxiliary power distribution networks. Installation is straightforward—simply connect control voltage to the solenoid and wire terminals to the load circuit for immediate operation. The 1 lb weight and compact form factor integrate seamlessly into engine compartments, battery boxes, or electrical panels without adding bulk or complexity.
