Blue Sea Contura SPDT 3-Position Panel-Mount Switch, Black
Blue Sea Contura SPDT 3-Position Panel-Mount Switch, Black
Momentary (ON)OFF(ON) Operation - Ignition Protected - Water Resistant

DESCRIPTION
Reliable Momentary Control for Demanding Marine and Off-Grid Panels
Engineered for critical electrical control in harsh environments, the Blue Sea Systems Contura SPDT switch delivers dependable (ON)OFF(ON) momentary switching. In electrical notation, brackets around the ON positions indicate momentary action. This means the actuator springs back to the central OFF position as soon as pressure is released, providing precise, temporary circuit activation ideal for equipment requiring active operator input.
Designed specifically to integrate into Blue Sea Systems water-resistant panels, this black Contura rocker switch is built to outperform standard automotive switches that quickly degrade when exposed to the elements. Whether you are outfitting a commercial vessel, upgrading a recreational boat, or building a rugged 4WD canopy electrical system, this component ensures long-term operational integrity.
Engineered for Harsh Marine Environments
Marine and off-road installations subject electrical components to constant mechanical stress and corrosive elements. Standard switches often fail due to internal corrosion from moisture ingress or contact failure caused by relentless pounding over waves and corrugations. This marine rocker switch incorporates an integrated panel mount gasket and a sealed construction that resists water, salt spray, and high humidity.
Furthermore, the switch is tested to withstand severe vibration, physical shock, and thermoshock. Rapid temperature fluctuations, such as cold sea spray hitting a warm console under the Australian sun, will not compromise the structural integrity of the housing or the reliability of the internal contacts.
Certified Ignition Protection for Enhanced Safety
When installing electrical switching near fuel sources, safety is paramount. Unsealed switches can create a microscopic arc when toggled, posing a severe hazard in enclosed compartments where petrol fumes may accumulate. This Contura switch features an enclosed housing that meets stringent UL1500 and ISO8846 ignition protection requirements. It is safe for installation aboard petrol-powered boats, significantly reducing the risk of vapour ignition in bilge areas, engine bays, or fuel-adjacent consoles.
Key Features and Benefits
- Dual Momentary (ON)OFF(ON) Action: Single Pole Double Throw (SPDT) configuration returns automatically to the centre OFF position, ideal for bi-directional momentary control.
- Certified Ignition Protected: Complies with UL1500 and ISO8846 standards for safe installation on petrol-powered vessels and near flammable vapour zones.
- Environmental Resilience: Built to resist moisture, salt spray, vibration, physical shock, and extreme temperature changes (thermoshock).
- Seamless Panel Integration: Specifically manufactured with a panel mount gasket to maintain a water-resistant seal in Blue Sea Systems Contura switch panels.
- Tactile and Secure: Features a textured black Contura actuator for confident grip in wet conditions and rear quick-connect spade terminals for efficient wiring.
Typical Applications
The momentary (ON)OFF(ON) switching pattern is essential for applications where a circuit must only remain active while the user is physically holding the switch. Common uses include:
- Anchor windlass up and down controls
- Trim tab adjustments and hydraulic jack plates
- Electric winches and hoists
- Motorised hatches, vents, and windscreen wipers
- Momentary horn, siren, or signalling circuits
Upgrade Your Control Panel
Equip your vessel or custom vehicle with switching hardware designed to survive the toughest conditions. Select the Blue Sea Contura SPDT (ON)OFF(ON) switch for your water-resistant panel installation to ensure safe, responsive, and lasting electrical control.
