Sea-Dog Double Gang Wall Switch Panel 403020-1 - 304 Stainless Steel, 12V, 2 SPDT Switches

The Sea-Dog 403020-1 is a double gang wall switch panel built for marine electrical systems that need two independent switch positions in one clean housing. It carries two black SPDT (single pole, double throw) switches, each rated for 12VDC at 15 amps, giving you two separate on-off controls for lighting, pumps, fans, or other 12-volt accessories from a single mounting plate. The panel itself is constructed of stamped 304 stainless steel, a corrosion-resistant material suited to the saltwater and high-humidity conditions found on boats, where standard plastic or painted-steel hardware tends to corrode or discolor over time.

The panel measures 2 inches by 2-1/2 inches by 1 inch, a compact footprint that fits into helm stations, cabin walls, and equipment panels without requiring a large cutout. It installs using two #6 RH fasteners (fasteners not included), so you will need to have these on hand or match them to your existing panel hardware. Because it is a double gang design, it is intended for installers who need to consolidate two switch functions into one panel opening rather than running two single-switch units side by side. This is a wall-mount unit, not a wired switch assembly with pre-terminated leads, so wiring is completed at installation to suit the specific 12-volt circuit being controlled.
