The Sea-Dog 420390-1 is a two position on-off push-pull switch built for marine electrical panels where a simple, reliable manual switch is needed. The switch operates with positive actuation between its two positions, On and Off, and is normally in the Off position. It is constructed of stamped brass for corrosion resistance in a marine environment. The switch measures 1 inch (dimension A) by 3/8 inch (dimension B) and is rated for a maximum panel thickness of 1 inch, making it suitable for standard helm and accessory panels. Electrically, it is rated 15 Amps at 12 Volts DC, suitable for lighting circuits, bilge pumps, accessory switching, and other low-voltage 12V DC marine circuits. The push-pull design mounts through a panel cutout and is operated by pulling the knob to close the circuit and pushing it in to open the circuit. As a Sea-Dog product, it is designed and sold for use aboard boats where dependable, water-resistant switching hardware is required.
