Sea-Dog On-Off-On SPDT Toggle Switch 15A 12V
Sea-Dog On-Off-On SPDT Toggle Switch 15A 12V — Product description
The Sea-Dog On-Off-On toggle switch is a single pole double throw unit rated for 15 amps at 12 volts DC. Flip it one way to feed one circuit, center it for a true off, flip it the other way for a second circuit. Three blade terminals, a black polycarbonate body, and non-lighted, so it draws nothing when it's off.
This is Sea-Dog's On-Off-On toggle switch, a single pole double throw unit rated for 15 amps at 12 volts DC. Flip the lever up and power goes one way. Center is off. Flip it down and power goes the other. That's what On-Off-On and SPDT mean in plain terms, one input and two selectable outputs with a true off in the middle.
Wiring is simple with three blade terminals on the back. The body is black polycarbonate with nylon internals and brass contacts, so it stands up to damp and salt air better than a bargain-bin switch. It's non-lighted, so there's no draw when it's sitting off.
It's a handy pick when you want to run one of two accessories from a single spot on the dash, or switch a circuit between two feeds. Think nav and anchor light selection, a two-speed fan, or any 12-volt load where you want a clean center-off. Don't overthink it. It does one job and does it well.

Frequently asked questions
What does On-Off-On mean on this switch?
It's a three-position lever. Up feeds one circuit, the center is fully off, and down feeds a second circuit. That center-off is the handy part, you get a clean cut with no power to either side.
How much power can this switch handle?
It's rated for 15 amps at 12 volts DC, which covers most small accessory loads like fans, lights, and blowers.
What kind of terminals does it use?
Three blade terminals on the back. Standard spade connectors slide right on, so wiring is quick.
Is this switch lighted?
No, it's non-lighted. That means zero current draw when the switch is in the off position.
What is it made of?
The housing is black polycarbonate with nylon internal parts and brass contacts, chosen to hold up to moisture and salt air.
