Sea-Dog DPDT On-Off-On Toggle Switch 15A | 420103-1 — Product description

The Sea-Dog 420103-1 is a marine-grade DPDT toggle switch with an on-off-on lever, rated 15 amps at 12 volts DC. Six blade terminals wire it in fast, and the brass and polycarbonate build shrugs off the salt air. It's the switch you reach for when you need to reverse a circuit or pick between two loads.

The Sea-Dog 420103-1 is a heavy-duty toggle switch built for the kind of wet, salty conditions that chew up cheap switches. It's an on-off-on design, so the lever gives you two live positions with a true off in the middle. That makes it the one you grab for reversing a circuit, running something forward and back, or picking between two loads from a single lever at the helm.

Rated for 15 amps at 12 volts DC, it handles most accessory circuits on a boat without breaking a sweat. Think bilge blowers, wipers, or a two-way pump setup. The six blade terminals wire in fast with standard 1/4-inch spade connectors, so there's no soldering to fuss with.

The body is brass, nylon, and polycarbonate, which means no bare steel sitting there waiting to rust. It's non-lighted and finished in black, low-key enough to disappear into any dash. Simple, tough, and it just does the job.

Frequently asked questions

What does On-Off-On mean on this switch?

The lever has three positions. Up and down are both live, and the center is off. It's the setup you want for reversing a circuit or switching between two loads.

What is a DPDT switch used for?

Double Pole Double Throw controls two separate circuits at once, or reverses the polarity of one. Common jobs are running something forward and reverse or picking between two power sources.

How much current can it handle?

It's rated for 15 amps at 12 volts DC. That covers most accessory circuits, blowers, wipers, and small pumps.

How do the terminals connect?

There are six blade terminals that take standard 1/4-inch spade connectors. You crimp them on, no soldering required.

Is this switch lighted?

No, it's a non-lighted switch with a black lever. If you need a backlit toggle, this one isn't it.
