Cole Hersee Sealed Rocker Switch Non-Illuminated SPDT On-Off-On 3 Blade

The Cole Hersee Sealed Rocker Switch Non-Illuminated SPDT On-Off-On 3 Blade is a heavy-duty electrical control component designed for demanding marine, automotive, and industrial applications where moisture and contamination pose a constant threat. This sealed rocker switch eliminates the need for protective housings by delivering IP66-rated sealing directly at the source, allowing operators to install reliable switching in wet environments, engine compartments, and high-pressure wash stations without compromising durability or performance.

Built with Single Pole, Double Throw (SPDT) switching architecture, this Cole Hersee unit delivers three independent brass blade terminals that enable three-position control—on, off, and on again—critical for applications requiring intermediate states or dual-load management. Its robust design handles 25 amps at 12V DC and 15 amps at 24V DC, making it suitable for auxiliary lighting circuits, pump controls, winch systems, and other power distribution tasks common in marine and tactical platforms. The non-illuminated design reduces parasitic drain and eliminates the complexity of backlit circuits, while the sealed construction with reinforced gasketry ensures water resistance even under high-pressure spray conditions.

Technicians, boat builders, and equipment integrators rely on Cole Hersee sealed rocker switches for mission-critical installations where switch failure is not an option. The three-blade terminal design accommodates both single-load and dual-load configurations, providing flexibility for custom harness builds in vehicles, vessels, and portable power systems. Installation requires minimal panel modification, and the robust rocker mechanism delivers positive tactile feedback under gloved operation, a necessity for tactical and maritime environments where operator awareness must remain high.
