Sea-Dog 420219-1 Contura Illuminated DPDT Momentary Rocker Switch, 20A 12V, 7-Blade Terminal

The Sea-Dog 420219-1 is a Contura illuminated rocker switch built for marine electrical panels that demand a momentary circuit action. It is wired DPDT (Double Pole, Double Throw) with a Momentary On/Off/Momentary On action, meaning the switch springs back to the center OFF position when released from either paddle direction, making it well suited for applications like trim tabs, windlass controls, or other functions requiring a spring-loaded momentary contact rather than a switch that stays latched in position. The switch is illuminated with a red light that displays when the switch is in the ON position, giving the operator clear visual confirmation at the helm or panel.

Construction is injection molded nylon and stamped brass with silver tin oxide contacts, rated 20A at 12VDC across 7 blade terminals. It carries an IP66 rating for the front panel components, and the switch body is built to resist vibration, shock, thermoshock, moisture, and salt spray, common hazards in a marine electrical environment. It is UL1500 and ISO8846 ignition protected for use in marine applications, and operates across a temperature range of -40 degrees C to +85 degrees C. The switch snaps into a standard Contura large rocker panel cutout, with panel dimensions of 13/16 inch by 1-7/16 inch, for a clean, finished installation.
