Sea-Dog 3-Position Marine Key Switch 420366-1
Sea-Dog 3-Position Marine Key Switch 420366-1 — Product description
The Sea-Dog 420366-1 is a universal 3-position marine ignition key switch that runs Off, Ignition, and Start. Molded polypropylene body, short shaft, three screw terminals, and it ships with two keys and a weather cap.
The Sea-Dog 3-position key switch is the part you reach for when your outboard or inboard finally quits turning over and you trace it back to a tired ignition switch. It runs Off, Ignition, and Start, so one twist powers up the gauges and the next kicks the starter. Let go and it springs back from Start on its own.
The body is molded polypropylene, which shrugs off the damp better than a bare metal housing, and it wires in through three screw terminals so you're not fighting crimp connectors at the helm. The short shaft suits a thinner dash or console panel where a long-barrel switch just won't sit flush. It's a universal fit, so it drops into most 12-volt boat setups.
Two keys and a weather cap come in the package. Keep one on the lanyard and stash the spare. If you've been jiggling a worn switch to coax out a spark, this is the honest fix.

Frequently asked questions
How many positions does this switch have?
Three. Off, Ignition, and Start. Turn to Ignition to power the circuits, then to Start to crank the engine. It springs back from the start position on its own.
How does it wire in?
Through three screw terminals on the back of the switch. That makes it easy to land your leads and service the connection later without special crimp tooling.
What is the housing made of?
Polypropylene. It handles the damp marine air and spray better than a bare metal body.
Does it come with keys?
Yes. Two keys and a protective cap are included in the package.
Will it fit my boat?
It's a universal short-shaft switch, so it fits most 12-volt boat panels. Measure your panel thickness against the short shaft before you order to be sure it seats flush.
