Featuring an \u003cstrong\u003e(ON)-OFF-ON switching configuration\u003c\/strong\u003e, this unit provides both momentary and maintained circuit activation separated by a central off position. It is an ideal component for custom 12V and 24V electrical dashboards in marine vessels, 4WDs, caravans, and commercial service vehicles.\u003c\/p\u003e\u003ch3\u003eEngineered for Harsh Environments\u003c\/h3\u003e\u003cp\u003eStandard automotive switches often fail prematurely when exposed to constant coastal air, heavy corrugations, or washdowns. The Contura 3 series mitigates the risk of electrical failure, contact corrosion, and water ingress through specialised environmental engineering. Constructed with a high-impact nylon housing and an integrated sealing gasket, this \u003cstrong\u003ewater-resistant rocker switch\u003c\/strong\u003e is rigorously tested to withstand extreme vibration, physical shock, thermoshock, moisture, and salt spray.\u003c\/p\u003e\u003cp\u003eThe ergonomic black actuator features a textured surface, ensuring positive tactile feedback and slip-resistant operation even when wearing gloves or operating a vessel in wet weather. Rear blade terminals allow for straightforward installation using standard quick-connect spade connectors, simplifying wiring harness integration and maintenance.\u003c\/p\u003e\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e(ON)-OFF-ON Action:\u003c\/strong\u003e Combines a momentary ON position (spring-return to centre) with a maintained ON position, separated by a central OFF state for versatile dual-function control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine-Grade Durability:\u003c\/strong\u003e Built to resist moisture, salt spray, and thermoshock, making it highly reliable for open-cockpit boats and exposed off-road dashboards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVibration and Shock Resistant:\u003c\/strong\u003e Maintains secure electrical contact across rough seas and corrugated Australian outback tracks without accidental tripping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeamless Panel Integration:\u003c\/strong\u003e Designed specifically to snap into Blue Sea Systems Contura Water Resistant Panels and Contura Switch Mounting Panels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eErgonomic Contura 3 Actuator:\u003c\/strong\u003e Textured black rocker face provides clear physical orientation and dependable grip in wet conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Blade Terminals:\u003c\/strong\u003e Rear spade connections support quick, secure wiring termination.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVersatile Switching Applications\u003c\/h3\u003e\u003cp\u003eBecause the (ON)-OFF-ON configuration offers both temporary and continuous circuit closure from a single pole, it reduces dashboard clutter by combining two operational modes into one footprint.
