Sea-Dog 420355-1 Three Position Brass Ignition Switch, Off-Ignition-Start, 3 Terminal with Cap

The Sea-Dog 420355-1 is a three position ignition switch built for off, ignition, and start functions on a boat's helm or dash panel. It uses a 13/16 inch diameter long shaft designed to fit through panels up to 1-1/8 inch thick, making it a straightforward replacement or upgrade for helm stations that need a reliable start switch. Electrical connection is made through three screw terminals, with the switch rated for 15 amps at 12 volts DC on the ignition circuit and 30 amps at 12 volts DC on the solenoid circuit, covering the demands of cranking an engine and running ignition-side accessories.

This switch is constructed of stamped brass for corrosion resistance and long service life in a marine environment, and it comes with a protective cap fitted over the switch face to help keep water and spray out of the terminal area. Two keys are included with every switch, and a blank replacement key (Sea-Dog 420399) is available separately if a spare or extra key is needed. The 420355-1 is part of Sea-Dog's three position ignition switch lineup, which also includes a version without the protective cap and a five-terminal magneto-style switch for different wiring setups.
