Designed to integrate seamlessly into Blue Sea Systems water-resistant panels, this single pole, double throw (SPDT) switch features a versatile \u003cstrong\u003e(ON)-OFF-ON\u003c\/strong\u003e three-position configuration. Note that brackets around an action denote a momentary position: the switch provides a momentary contact in the first position, a stable centre off, and a maintained latch in the opposite position. This makes it an ideal choice for dual-mode circuits such as bilge pumps (manual momentary override vs. automatic float switch operation), windscreen wipers, or navigation light configurations.\u003c\/p\u003e\u003ch3\u003eEngineered for Harsh Marine and Off-Road Environments\u003c\/h3\u003e\u003cp\u003eStandard automotive switches frequently succumb to corrosion, contact failure, and water ingress when exposed to coastal air or rough corrugations. The Blue Sea Contura series mitigates these risks through dedicated environmental sealing and robust internal construction. Built with an integrated mounting gasket, the switch resists high-pressure washdowns, heavy salt spray, and relentless moisture when properly mounted in a compatible panel.\u003c\/p\u003e\u003cp\u003eFurthermore, its internal mechanism is tested against extreme vibration, physical shock, and thermoshock. Whether mounted in an exposed centre console boat helm experiencing rapid temperature shifts or a touring canopy subject to severe off-road vibrations, this Contura rocker switch maintains reliable electrical continuity and crisp tactile actuation.\u003c\/p\u003e\u003ch3\u003eCertified Ignition Protection for Petrol Vessels\u003c\/h3\u003e\u003cp\u003eElectrical arcing inside an unsealed switch housing presents a significant hazard in enclosed spaces where flammable fumes may accumulate. This Blue Sea Contura switch is fully ignition protected, complying with stringent \u003cstrong\u003eUL1500 and ISO8846 safety standards\u003c\/strong\u003e. It is safe for installation aboard petrol-powered boats, engine bays, and battery compartments, offering peace of mind for marine electricians and vessel owners alike.\u003c\/p\u003e\u003ch3\u003eKey Features \u0026amp; Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile (ON)-OFF-ON Action:\u003c\/strong\u003e Combines momentary and maintained switching in a single SPDT housing for complex circuit control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertified Ignition Protected:\u003c\/strong\u003e Meets UL1500 and ISO8846 requirements, reducing fire risks in petrol-powered marine vessels and fuel storage areas.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtreme Environmental Resistance:\u003c\/strong\u003e Engineered to withstand constant exposure to salt spray, moisture, severe vibration, mechanical shock, and thermoshock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eErgonomic Contoured Actuator:\u003c\/strong\u003e The grey rocker features tactile horizontal ridges for confident, slip-free operation in wet conditions or low visibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStreamlined Installation:\u003c\/strong\u003e Equipped with rear blade terminals for standard quick-connect electrical wiring and an integrated gasket for a watertight panel seal.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePractical Applications in 12V and 24V Systems\u003c\/h3\u003e\u003cp\u003eWhile purpose-built to snap directly into Blue Sea Systems water-resistant Contura panels, this switch is equally suited to custom marine dashboards, caravan control hubs, and 4x4 dual battery canopies utilising standard rectangular rocker cutouts.
