Sea-Dog 420104-1 DPDT Toggle Switch, Momentary On/Off/Momentary On, 15 Amp 12 Volt

The Sea-Dog 420104-1 is a DPDT (double pole, double throw) toggle switch built for momentary on/off/momentary on circuit control, where the switch springs back to the center off position when released from either throw. This action makes it well suited for controlling functions that should only run while the toggle is actively held, such as trim, windlass direction, or other momentary-duty marine circuits, while still allowing a stable off position at center.

The switch is constructed of stamped brass, injection molded nylon, and polycarbonate for corrosion resistance in a marine environment. It is water resistant, featuring a locking ring with a lever seal and a protruding cap nut for a secure, sealed panel installation. The switch has 6 blade terminals and is rated for 15 amps at 12 volts DC, with terminal spacing of 3/8 inch by 1/2 inch. It panel mounts for a clean installation on a helm, console, or accessory panel.
