Cole Hersee Rocker Switch SPDT On-Off-On 3 Blade

The Cole Hersee Rocker Switch SPDT On-Off-On 3 Blade is a heavy-duty electrical control switch purpose-built for marine vessels and demanding electrical systems. After years running boats on saltwater and freshwater alike, reliable deck hardware makes the difference between a smooth outing and a frustrating day on the water. This three-position rocker switch handles the switching demands of navigation lights, bilge pumps, windlass controls, and auxiliary systems where you need momentary or sustained activation in both directions.

This SPDT (single-pole, double-throw) design delivers 20 amps at 12VDC and 15 amps at 24VDC, making it compatible with standard marine electrical systems whether you're running a center console, cruiser, or larger offshore vessel. The switch features sealed contact areas rated to IP66—meaning it withstands high-pressure washdowns, salt spray, and humidity that would kill inferior components in months. The compact three-blade rocker mechanism provides positive tactile feedback and is sealed against moisture intrusion, a critical feature for any switch exposed to the harsh marine environment where corrosion claims countless hours of maintenance and repair work.

Professional boat builders, charter operators, and serious recreational anglers trust Cole Hersee switches for panel installation and retrofit applications where durability and reliability are non-negotiable. The weatherproof construction ensures years of dependable service in pilothouse consoles, engine room panels, and exposed helm stations. Whether you're upgrading an older vessel or building a new system from scratch, this SPDT rocker switch provides the robust switching control that marine electrical systems demand, backed by the proven performance standards that have made Cole Hersee the industry standard for marine electrical hardware.
