Sea-Dog 420211-1 Illuminating Contura Rocker Switch, On/Off SPST, 12 Volt 20 Amp

The Sea-Dog 420211-1 is an illuminating Contura-style rocker switch built for marine electrical panels where a durable, water-resistant switching point is required. It operates as a simple On/Off SPST (single pole, single throw) switch, making it a straightforward replacement or addition for lighting circuits, pumps, fans, and other single-circuit accessories aboard a boat. The switch body is constructed of stamped brass, injection molded nylon, and polycarbonate for corrosion resistance and long service life in a marine environment. It is rated for 12 Volts DC at 20 Amps, giving it enough capacity for most 12V accessory circuits found on boats. The switch is ignition protected and water resistant, carrying an IP54 ingress protection rating, so it can be mounted in helm stations, dash panels, and other areas exposed to spray. It mounts in a standard panel cutout using a plug-in connector for quick wiring, and its illuminated design allows the switch to be identified in low light or nighttime operation at the helm. Finished in black, it is intended for panel mount installation alongside other Contura-style switches for a clean, uniform look on a custom or replacement switch panel.
