Blue Sea Systems Contura III DPDT On-Off-On Rocker Switch, Gray - Combining Nav Lights with Anchor Light, 8220

The Blue Sea Systems Contura III DPDT On-Off-On rocker switch (part number 8220) is a water-resistant, double-pole double-throw switch built for combining navigation lights with an anchor light on a shared bulb circuit. It is specially manufactured for mounting in Blue Sea Systems water-resistant switch panels, giving the boat owner a single control point for switching between running-light configurations without adding a separate switch for the anchor light function.

Rated for 20 Amps at 24 Volts, the switch uses phosphor bronze contacts for reliable, low-resistance connections and terminates via screw terminals for a secure wiring connection. The gray plastic housing carries an IP54 ingress protection rating and meets CE and UL specifications, and the switch is built to resist vibration, shock, thermoshock, moisture, and salt spray, making it suited to the marine and RV electrical environment. The three-position On-Off-On operation allows the DPDT contacts to combine navigation lighting circuits with an anchor light using a shared bulb, giving a clean, purpose-built control for boats that need this lighting combination.
