Featuring a Double-Pole Double-Throw (DPDT) configuration with an \u003cstrong\u003e(ON)-OFF-ON\u003c\/strong\u003e action, this switch offers a momentary ON position, a central OFF state, and a maintained ON position. Note that in standard electrical terminology, parentheses indicate a momentary action, returning to the central off position when released. This specific three-position layout is ideal for complex switching tasks, such as combining windlass controls, trim tabs, or dual-circuit bilge pump operations where both manual override and continuous automated circuits are managed from a single actuator.\u003c\/p\u003e\u003ch3\u003eEngineered for Harsh Marine and Off-Road Environments\u003c\/h3\u003e\u003cp\u003eStandard automotive switches often fail prematurely when exposed to coastal environments due to internal corrosion and mechanical fatigue. This Contura rocker switch is purpose-built to eliminate those failure points. It undergoes rigorous testing to withstand extreme vibration, physical shock, and thermoshock (rapid temperature fluctuations). Furthermore, its internal components are sealed against moisture and corrosive salt spray, reducing the risk of short circuits and voltage drop over time.\u003c\/p\u003e\u003cp\u003eDesigned specifically for seamless integration into \u003cstrong\u003eBlue Sea Systems water-resistant panels\u003c\/strong\u003e, the switch includes an integrated rubber mounting gasket. This ensures a tight, weatherproof seal at the panel face, protecting your behind-the-dash wiring and busbars from water ingress during washdowns or heavy seas.\u003c\/p\u003e\u003ch3\u003eCertified Ignition Protection for Maximum Safety\u003c\/h3\u003e\u003cp\u003eWhen installing electrical components in enclosed spaces or aboard petrol-powered vessels, preventing stray sparks is critical. This switch is fully \u003cstrong\u003eignition protected\u003c\/strong\u003e, meeting stringent UL1500 and ISO8846 safety standards. The enclosed housing ensures that any internal arcing during switching cannot ignite surrounding flammable vapours, making it safe for installation in engine bays, fuel tank compartments, and battery boxes.\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 DPDT unit for multi-function control across two separate circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine-Grade Durability:\u003c\/strong\u003e Impervious to moisture, salt spray, vibration, shock, and extreme temperature shifts for long-term reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertified Ignition Protected:\u003c\/strong\u003e Complies with UL1500 and ISO8846 standards for safe installation aboard petrol-powered boats and near battery banks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTactile Ergonomics:\u003c\/strong\u003e Features a grey textured Contura rocker actuator with raised ribs for confident, slip-free operation in wet conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure Connectivity:\u003c\/strong\u003e Equipped with rear spade terminals for straightforward, reliable double-pole wiring and panel integration.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cp\u003eWhile specially manufactured as a direct replacement or upgrade for Blue Sea Systems water-resistant switch panels, this robust DPDT rocker switch is also widely used in custom dash layouts for:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCommercial and recreational marine vessels\u003c\/li\u003e\n\u003cli\u003e4WD canopies, camper trailers, and off-road caravans\u003c\/li\u003e\n\u003cli\u003eEmergency and utility service vehicles\u003c\/li\u003e\n\u003cli\u003eIndustrial control panels exposed to the elements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eUpgrade Your Control Panel\u003c\/h3\u003e\u003cp\u003eEnsure safe, reliable circuit management in the harshest conditions.
