This single pole double throw (SPDT) toggle switch provides a dependable ON-OFF-ON switching action, allowing you to control two separate circuits from a single common source, with a positive centre-off position for complete isolation. Whether you are configuring dual-speed windscreen wipers, managing manual and automatic bilge pump overrides, or wiring up generator starter controls, this switch delivers the tactile feedback and mechanical reliability required for critical applications.\u003c\/p\u003e\n\n\u003ch3\u003eSeamless Integration with A-Series Panels\u003c\/h3\u003e\n\u003cp\u003eOne of the primary challenges when upgrading or building a custom power distribution panel is maintaining a clean, uniform aesthetic across different types of circuit protection and control switches. This toggle switch is specifically engineered to mount directly into standard Blue Sea Systems A-Series toggle circuit breaker apertures. By matching the physical footprint and white toggle actuator style of A-Series breakers, it allows system builders to integrate non-breaker switching functions into an existing panel layout without visual mismatches or awkward panel modifications.\u003c\/p\u003e\n\u003cp\u003eFor installations that do not utilise pre-cut circuit breaker panels, the switch includes a specialised black panel-mount adapter frame. This supplied adapter allows the unit to be securely fitted into a standard 5\/8-inch (approx. 16mm) circular mounting hole, providing exceptional versatility for custom dashboards, helm stations, and auxiliary control boxes.\u003c\/p\u003e\n\n\u003ch3\u003eEngineered for Harsh Environments\u003c\/h3\u003e\n\u003cp\u003eStandard automotive switches often fail prematurely when exposed to high-humidity, salt-laden air, or constant vibration. Sub-standard materials can quickly oxidise, leading to increased electrical resistance, intermittent circuit failure, and potential overheating at the terminal connections. To mitigate these risks, this switch is constructed from high-grade, non-corrosive nickel-plated brass and a robust phenolic body.\u003c\/p\u003e\n\u003cp\u003ePhenolic resin is an advanced thermosetting plastic renowned for its superior electrical insulation properties, high heat resistance, and mechanical strength. Combined with the corrosion-resistant nickel-plated brass hardware and quick-connect spade terminals, this construction ensures consistent electrical conductivity and structural integrity over thousands of switching cycles in demanding marine and mobile environments.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSPDT ON-OFF-ON Configuration:\u003c\/strong\u003e Provides versatile three-position control, ideal for switching between two power sources or operating two-function accessories like high\/low fans and manual\/auto bilge systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Panel Compatibility:\u003c\/strong\u003e Designed to drop directly into standard A-Series toggle circuit breaker panel cutouts for a unified, professional helm or dashboard appearance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupplied Mounting Adapter:\u003c\/strong\u003e Includes a dedicated adapter bezel to fit standard 5\/8-inch (approx. 16mm) round mounting holes in custom panels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Corrosive Construction:\u003c\/strong\u003e Built with a phenolic housing and nickel-plated brass components to resist moisture, salt mist, and oxidation in marine environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Connect Terminals:\u003c\/strong\u003e Features rear spade terminals for straightforward, secure wiring connections during installation or maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCommon Applications\u003c\/h3\u003e\n\u003cp\u003eThe three-position maintained contact arrangement makes this switch a versatile component for a wide range of low-voltage control circuits, including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBilge Pump Control:\u003c\/strong\u003e Easily switch between Automatic (float switch), Off, and Manual override modes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNavigation and Anchor Lights:\u003c\/strong\u003e Control running lights and anchor lights independently from a single toggle location.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper and Fan Controls:\u003c\/strong\u003e Manage multi-speed motors or directional actuators in boats, RVs, and heavy machinery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine and Generator Systems:\u003c\/strong\u003e Ideal for auxiliary start\/stop controls, fuel transfer pumps, and horn relays.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eUpgrade Your Control Panel\u003c\/h3\u003e\n\u003cp\u003eEnsure your electrical distribution system operates safely and reliably in any environment.
