Designed specifically for systems where the pole configuration must remain separate from the primary circuit protection, this three-position ON-OFF-ON switch provides reliable control over dual circuits or multi-state equipment.\u003c\/p\u003e\u003cp\u003eWith a tactile white toggle lever mounted on a sleek black adapter plate, this switch offers clear visual and physical status indication. Whether you are outfitting a commercial marine vessel, a recreational boat, a custom caravan, or an industrial control panel, this component delivers the precise circuit management required for demanding electrical environments.\u003c\/p\u003e\u003ch3\u003eSeamless Integration with A-Series Panels\u003c\/h3\u003e\u003cp\u003eAchieving a uniform, professional aesthetic on an electrical distribution panel can be difficult when mixing circuit breakers with dedicated control switches. This toggle switch solves that design challenge by mounting directly into standard Blue Sea Systems A-Series toggle circuit breaker apertures. It is supplied with a specialised mounting adapter that accommodates a standard 5\/8-inch (Approx. 16mm) circuit breaker mounting hole. This allows system builders and marine electricians to maintain a clean, cohesive dashboard or switchboard layout without requiring custom fabrication or mismatched hardware.\u003c\/p\u003e\u003ch3\u003eEngineered for Harsh Marine Environments\u003c\/h3\u003e\u003cp\u003eElectrical switches used in marine, coastal, and mobile applications are constantly exposed to moisture, salt-laden air, and vibration. Standard automotive hardware often suffers from rapid oxidation, leading to high resistance, voltage drop, or complete mechanical failure. To mitigate these risks, the Blue Sea DPDT switch is manufactured from non-corrosive nickel-plated brass and high-grade phenolic materials. This robust construction resists degradation over time, ensuring dependable electrical conductivity and smooth mechanical actuation in damp bilges, open cockpits, and off-grid battery enclosures.\u003c\/p\u003e\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble-Pole Double-Throw (DPDT) Configuration:\u003c\/strong\u003e Controls two independent circuits simultaneously or manages polarity reversal and dual-input selection with a single actuator.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree-Position ON-OFF-ON Action:\u003c\/strong\u003e Features a positive centre-off position to prevent accidental activation when transitioning between two active states.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA-Series Panel Compatibility:\u003c\/strong\u003e Designed to match the footprint and aesthetic of A-Series toggle circuit breakers for a unified panel appearance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Mounting Adapter:\u003c\/strong\u003e Supplied ready to fit into a standard 5\/8-inch (Approx. 16mm) circuit breaker cutout for straightforward installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Corrosive Construction:\u003c\/strong\u003e Built from durable nickel-plated brass and phenolic materials to withstand harsh marine and mobile conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Visibility Actuator:\u003c\/strong\u003e The contrasting white toggle lever provides immediate visual confirmation of the switch position.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Control Applications\u003c\/h3\u003e\u003cp\u003eBecause a DPDT switch can route two separate inputs to two separate outputs, it is exceptionally versatile for complex 12V and 24V DC control wiring, as well as applicable AC control circuits.
