Featuring a momentary (ON)-OFF-(ON) three-position configuration, the actuator springs back to the centre OFF position when released. This provides safe, deliberate control for dual-direction circuits where continuous activation is not desired.\u003c\/p\u003e\u003cp\u003eStandard automotive switches often fail quickly when exposed to coastal air, hull pounding, or rapid temperature shifts, leading to corroded contacts and electrical faults. The Contura series solves this problem by integrating internal weather-resistant seals and rugged internal mechanisms designed to endure constant vibration, physical shock, thermoshock, moisture, and salt spray.\u003c\/p\u003e\u003ch3\u003eEngineered for Marine Safety and Panel Integration\u003c\/h3\u003e\u003cp\u003eWhen working with marine electrical systems, particularly aboard petrol-powered vessels, safety compliance is critical. This switch features a fully sealed, ignition-protected housing that meets strict UL 1500 and ISO 8846 standards. It reduces the risk of internal electrical arcs igniting flammable bilge fumes, making it safe for installation in or near engine compartments and fuel storage areas.\u003c\/p\u003e\u003cp\u003eIn addition to standalone custom dash installations, this unit is specially manufactured to clip directly into Blue Sea Systems water-resistant Contura panels, ensuring a cohesive, watertight seal across your entire helm or control board.\u003c\/p\u003e\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMomentary (ON)-OFF-(ON) Action:\u003c\/strong\u003e Spring-return to the centre off position prevents accidental continuous operation of pumps, winches, or actuators.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertified Ignition Protection:\u003c\/strong\u003e Complies with UL 1500 and ISO 8846 requirements for safe installation aboard petrol and diesel boats.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtreme Environmental Resistance:\u003c\/strong\u003e Tested to withstand heavy vibration, mechanical shock, thermoshock, moisture ingress, and corrosive salt spray.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeamless Panel Mounting:\u003c\/strong\u003e Purpose-built for direct integration into Blue Sea Systems water-resistant electrical panels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTactile Grey Rocker Face:\u003c\/strong\u003e Provides positive physical feedback in wet conditions and rough seas while matching standard marine dash aesthetics.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cp\u003eBecause the (ON) positions in parentheses denote momentary operation, this SPDT switch is suited for equipment that requires temporary, two-way or dual-circuit control:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWindlass anchor winches (Up \/ Off \/ Down)\u003c\/li\u003e\n\u003cli\u003eHydraulic or electric trim tabs and engine tilt controls\u003c\/li\u003e\n\u003cli\u003eDual-circuit bilge pump overrides or momentary horn and wiper washer functions\u003c\/li\u003e\n\u003cli\u003eMotorised hatches, vents, and linear actuators in marine vessels, 4WDs, and expedition campers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eUpgrade Your Control Panel\u003c\/h3\u003e\u003cp\u003eEquip your vessel or off-road electrical system with hardware built to handle the elements.
