Blue Sea Systems Contura III SPST Off-(On) Rocker Switch, Gray - Water Resistant Marine Panel Switch (8231)

The Blue Sea Systems Contura III switch, part number 8231, is a water resistant SPST Off-(On) momentary rocker switch finished in gray, built for mounting in Blue Sea Systems Contura Water Resistant Panels and Contura Switch Mounting Panels. As a single pole single throw switch with a momentary ON position, it returns to OFF when released, making it well suited to functions like a horn or windshield wipers where the circuit should only be live while the switch is held.

The switch body is molded plastic with screw terminal connections and a normally open contact configuration for straightforward wiring into a 12 or 24 volt DC marine electrical system. It is rated for 20 amps at 12 volts DC or 15 amps at 24 volts DC, and it carries a CE mark and meets UL 1500 and ISO 8846 external ignition protection requirements, making it appropriate for use near gasoline engines and fuel systems. Blue Sea Systems built the Contura III to resist vibration, shock, thermoshock, moisture, and salt spray, conditions typical of an open helm or engine compartment.

This switch has a single position and mounts into a panel cutout alongside other Contura switches, letting boat owners standardize their helm or breaker panel with a matched set of gray rocker switches.
