Sea-Dog Contura On-Off-On DPDT Rocker Switch 12V 20A
Sea-Dog Contura On-Off-On DPDT Rocker Switch 12V 20A — Product description
Sea-Dog's Contura rocker switch handles on-off-on duty in a double pole double throw layout, rated 12V DC at 20 amps. A red pilot light tells you at a glance when it's live, and the IP66-sealed body shrugs off spray at the helm. Seven blade terminals give you the wiring flexibility for reversing motors or two-way circuits.
If you've spent any time rewiring a helm, you know the Contura form factor. It's the flush rocker that drops into a standard panel cutout and sits clean next to your other switches. This one from Sea-Dog is the on-off-on version, wired double pole double throw, so a single rocker can send power two different ways with a dead-center off in between.
That on-off-on DPDT setup is what makes it handy for reversing jobs. Think trim motors, actuators, or any two-way circuit where you want up on one side, off in the middle, and down on the other. Push it one way and the top pair of contacts closes. Push it the other and the bottom pair takes over. Seven blade terminals give you the room to wire it that way without cramming everything onto one lug.
It's rated for 12 volts DC at 20 amps, which covers most accessory loads you'll run at a small-boat helm. The red pilot light glows when the circuit is live, so you're not squinting at the panel wondering if you left something on. Handy at night, handier still when you're chasing down a wiring gremlin.
Sea-Dog built the body from brass contacts with nylon and polycarbonate housing, and sealed it to IP66. That means it takes dust and heavy spray without letting water reach the contacts. The operating range runs from -40 all the way to 85 degrees Celsius, so it holds up whether you're on a cold northern lake in spring or a sun-baked console down south.
Wire it into a switch panel, a dash, or a custom console. The black finish keeps it low-key next to gauges and other Contura-style rockers. It's a straightforward, sealed switch that does one job well and keeps doing it season after season.
One note on wiring: with DPDT you've got two circuits moving together. Double-check your terminal map before you power up, especially if you're using it to reverse a motor. Get the pairs right and it's a clean, reliable install.

Frequently asked questions
What does on-off-on mean on this switch?
The rocker has three positions. Press one side for the first circuit, leave it centered for off, and press the other side for the second circuit. It's the layout you want for reversing or two-way jobs.
Is this switch waterproof?
It carries an IP66 rating, which means it's sealed against dust and strong water jets. It handles the spray you'll see at an open helm, though it isn't meant for full submersion.
What loads can I run on it?
It's rated for 12 volts DC at 20 amps. That covers most accessory and small motor loads at a typical helm. Just stay within that amperage.
Why does it have seven terminals?
Double pole double throw means two independent circuits switching together, so it needs more blade terminals than a simple on-off switch. The seven blades let you wire both poles plus the light.
Will it fit a standard rocker panel?
Yes. It uses the common Contura-style cutout, so it drops into standard rocker openings and sits flush next to matching switches.
Can I use it to reverse a motor?
The on-off-on DPDT layout is a common choice for reversing polarity on trim motors and actuators. Map your terminals carefully before powering up so the pairs switch the way you intend.
What temperatures can it handle?
The switch is rated from -40 to 85 degrees Celsius, so it works through cold mornings and hot, sun-baked console conditions alike.
