Sea-Dog Magneto Ignition Switch with Choke | 420383-1
Sea-Dog Magneto Ignition Switch with Choke | 420383-1 — Product description
Worn-out key switch on a magneto outboard? This Sea-Dog magneto-style switch drops right in with the classic Off-Ignition-Start layout plus a built-in push choke. Six screw terminals, a polypropylene housing that shrugs off spray, and two keys in the box.
If you've got an outboard with magneto ignition and the old key switch is worn out, cracked, or just won't turn clean anymore, this is the Sea-Dog replacement that drops right in. It's a magneto-style ignition switch with the classic Off-Ignition-Start layout plus a built-in choke, so you're running the whole starting sequence off one key.
Here's how it works. Turn to Ignition to power up, turn to Start to crank, and on a cold morning you push the key in to choke the engine while it fires. Let off and the switch springs back to the run position. It's the same simple routine you already know, and there's nothing electronic to fail on you out there.
The switch wires in through six screw terminals, which cover the magneto, ignition, start, and choke circuits. That's the full set you need for a magneto engine, so you're not adapting or splicing to make it fit the harness. The housing is polypropylene, so it shrugs off salt air, spray, and the damp that lives behind every console. The shaft is short, which suits a thinner dash panel where you don't have a lot of depth to work with behind the helm.
Two keys come in the package, so you've got a spare from day one. Toss one in the glovebox or hand it to whoever else runs the boat.
A couple of honest notes. This is a magneto-style switch, meaning it grounds the magneto to shut the engine down. If your engine uses a battery-powered ignition instead, this isn't the right switch, and forcing it will leave you scratching your head at the ramp. When in doubt, check your engine's ignition type or send us the model and we'll tell you straight. And before you wire it in, snap a photo of your old switch's terminals. Matching the wires back one at a time is the surest way to get it right the first time.

Frequently asked questions
What does 'magneto style' mean on this switch?
It's built for engines with magneto ignition. Instead of cutting battery power, the switch grounds the magneto to shut the engine down. If your outboard runs a battery-powered ignition, this isn't the right switch for it.
How does the choke work?
There's no separate choke knob. You push the key in to choke the engine while you crank it on a cold start, then let off once it's running. One key handles the whole sequence.
What wires connect to the switch?
It has six screw terminals covering the magneto, ignition, start, and choke circuits. Before you pull the old switch, photograph its wiring so you can match each wire back to the same terminal.
Does it come with keys?
Yes, two keys ship with the switch, so you've got a spare right away.
What's the housing made of?
Polypropylene. It holds up to salt air, spray, and the damp that collects behind a console far better than a bare metal switch would.
Will the short shaft fit my dash?
The short shaft suits thinner panels where there isn't much room behind the helm. Measure your panel thickness and the mounting hole before ordering. If you're unsure, send us your setup and we'll confirm the fit.
