Sierra RK40660B Marine Rocker Switch – On-On, DPST, Blue Halo LED, IP68
The Sierra RK40660B is a premium illuminated marine rocker switch combining IP68 waterproof sealing with dual-zone LED lighting for a clean, modern helm panel appearance. The blue halo LED illuminates the perimeter of the switch for a distinctive backlit look, while the rocker actuator itself is independently illuminated — giving you both panel ambiance and clear switch-state visibility in low-light conditions.
The On-On DPST configuration switches two circuits simultaneously between two positions, with no off position — ideal for applications where you need to select between two active states. Rated at 20A at 12V DC, it handles high-current marine loads. The dedicated TE connector with .110 terminals provides a secure, vibration-resistant wiring connection. Fits industry-standard panel cutouts for straightforward installation in new builds and retrofits alike.

Parts Desk Insights
The RK40660B is the right choice when you want a high-current illuminated rocker with a blue halo LED and an On-On DPST configuration — a setup used when you need to switch two circuits together between two active states with no off position. The dual-zone illumination (perimeter halo plus actuator backlight) makes it one of the more visually distinctive switches available for a modern helm build. If you need a non-illuminated rocker switch for the same panel, the Sierra Contura XIV series offers IP66/68-sealed options across a wide range of circuit configurations.
