Sea-Dog 420248-1 Large Rocker Switch, SPDT On/Off/On, 15 Amp 12 Volt

The Sea-Dog 420248-1 is a large panel-mount rocker switch built for marine electrical circuits that need a simple, durable on/off/on control. It uses an SPDT (single pole, double throw) switching arrangement with 3 blade terminals, giving it an On/Off/On action so a single switch can control two separate circuit functions from one panel position. The switch is rated 15 Amps at 12 Volts DC, suitable for typical 12V boat accessory and lighting circuits.

Construction is injection molded nylon and stamped brass, with polycarbonate used in the housing. The rocker snaps directly into a standard 7/8 inch by 1-7/16 inch panel slot without additional mounting hardware, and wiring connects via 1/4 inch blade terminals for a quick, solderless installation. The switch is finished in black. Overall item dimensions are 4.94 x 1.88 x 1.25 inches, and the unit weighs 0.064 pounds.

This switch is part of a Sea-Dog rocker switch series sharing the same body, panel cutout, and terminal style, with different internal circuits (SPST, DPDT, SPDT maintained, and SPDT momentary) available depending on the control function needed.
