The \u003cstrong\u003eBlue Sea SPDT (ON)OFF(ON) Toggle Switch\u003c\/strong\u003e provides precise manual actuation for applications demanding a momentary, dual-throw switching arrangement. In electrical nomenclature, parentheses around the \"ON\" state signify a momentary action. This means the white toggle actuator stays in a central OFF resting position and only energises the selected circuit while actively held in either of the two ON positions, automatically returning to the centre when released.\u003c\/p\u003e\u003cp\u003eThis specific switching logic is vital for systems that require temporary engagement in two different modes or directions. It eliminates the risk of accidentally leaving a high-draw or sensitive circuit engaged, protecting starter motors, pumps, and actuators from burnout or battery drain.\u003c\/p\u003e\u003ch3\u003eEngineered for Seamless A-Series Panel Integration\u003c\/h3\u003e\u003cp\u003eAchieving a uniform, factory-grade finish on custom dashboards and power distribution boards can be challenging when mixing circuit breakers and standard switches. This unit is specifically designed to mount directly into standard Blue Sea Systems A-Series toggle circuit breaker apertures. It includes a pre-drilled black faceplate that matches the footprint of A-Series breakers, allowing system builders to maintain a clean, consistent aesthetic across the entire panel without awkward gaps or mismatched hardware.\u003c\/p\u003e\u003cp\u003eFor versatile installation across custom helm stations, caravan control boards, or industrial enclosures, the switch also comes supplied with a dedicated mounting adapter. This allows seamless fitment into a standard 5\/8-inch (approx. 16mm) circuit breaker mounting hole, secured firmly via a threaded bushing and knurled nut.\u003c\/p\u003e\u003ch3\u003eKey Features and Technical Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMomentary SPDT Configuration:\u003c\/strong\u003e Single Pole Double Throw (ON)OFF(ON) action provides temporary circuit activation in two distinct directions from a central off position.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA-Series Aperture Compatibility:\u003c\/strong\u003e Mounts flush into A-Series toggle circuit breaker cutouts for a unified panel layout.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Mounting Adapter:\u003c\/strong\u003e Includes an adapter to fit standard 5\/8-inch (approx. 16mm) circular mounting holes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion-Resistant Materials:\u003c\/strong\u003e Constructed from nickel-plated brass and a durable phenolic body to withstand harsh marine and mobile environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick Connect Termination:\u003c\/strong\u003e Equipped with rear flat tab terminals designed for standard spade connectors, simplifying wiring and maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBuilt for Harsh Marine and Mobile Environments\u003c\/h3\u003e\u003cp\u003eStandard automotive switches often fail prematurely when exposed to salt air, high humidity, and constant vibration. Constructed with a non-corrosive nickel-plated brass bushing and a heavy-duty phenolic housing, this toggle switch resists oxidation and mechanical wear.
