Blue Sea 9012 L Solenoid Switch - 12-24VDC - 250A

The Blue Sea 9012 L Solenoid Switch is a marine-grade electrical control device engineered for 12-24VDC systems handling up to 250A of load capacity. This component serves boaters and anglers who need reliable remote engine isolation or accessory management from the helm without running multiple heavy-gauge wires throughout the vessel. Whether you're outfitting a center console fishing boat, a cruiser, or restoring vintage marine systems, a quality solenoid switch eliminates the need for manual battery disconnect switches at the engine compartment and provides the foundation for modern marine electrical architecture.

Built with hermetically sealed contacts and a vaporproof design, the Blue Sea 9012 resists the corrosive salt spray and moisture intrusion that damage standard electrical components in marine environments. Its ignition-protected construction makes it safe for gasoline-powered vessel installations—a critical safety feature that prevents spark ignition risk in fuel-rich engine compartments. The switch activates through any standard ON-OFF control switch positioned anywhere on the boat, from the wheelhouse to the helm console, enabling convenient engine kill capability without returning to the engine bay. The integrated coil design and robust 250A rating handle high-inrush starter demands and multiple battery banks typical of modern fishing and cruising vessels.

Anglers running overnight trolling setups, cruisers with dual-battery systems, and boaters retrofitting modern kill-switch technology will find the Blue Sea 9012 delivers professional-grade reliability without compromise. Its compact footprint (4 x 3 x 7 inches) fits engine compartments with space constraints, while the lightweight 1-pound design simplifies mounting. Compatible with both 12V and 24V DC systems, this solenoid integrates seamlessly into new builds or existing marine electrical panels, providing the isolation and control that separates casual boaters from safety-conscious mariners who demand redundancy and peace of mind on the water.
