Sea-Dog 3-Way Bilge Pump Switch, 12V, 20A Breaker
Sea-Dog 3-Way Bilge Pump Switch, 12V, 20A Breaker — Product description
The Sea-Dog three-way bilge pump switch puts Auto, Manual, and Off control on one panel for your 12-volt bilge pump. A built-in LED tells you when the pump's running, and the 20-amp circuit breaker protects the circuit. The corrosion-resistant ABS housing is built for life on the water.
Every boat with a bilge pump needs a clean way to control it, and that's exactly what the Sea-Dog three-way switch does. You get three positions from one panel: Auto, Manual, and Off. In Auto, the pump runs on its own when the water comes up. Flip to Manual when you want to clear the bilge yourself. And Off keeps it from cycling when the boat's on the trailer or in storage. Simple, and it's the way most of us actually run a bilge.
The built-in LED indicator is the part you'll appreciate underway. One glance at the dash tells you the pump is drawing power and doing its job. No more wondering whether that pump kicked on, or leaning over the transom to listen for it. That little light saves you a lot of second-guessing when the weather turns and water's coming aboard.
Wiring is straightforward. The switch handles a 12-volt DC circuit, and there's a 20-ampere circuit breaker built right in, so you don't need to add a separate inline fuse for the pump. If the pump jams on debris and pulls too much current, the breaker trips instead of cooking your wiring. Reset it and you're back in business. It's the kind of protection you want on a circuit that lives down in a wet, hard-to-reach spot.
Sea-Dog built the housing from corrosion-resistant ABS, so it holds up to the damp, salty air that eats cheaper hardware alive. This is a helm or console mount, and it fits the same spots most anglers and cruisers already run their accessory switches. Whether you're rigging a new center console, a bass boat, or refreshing the panel on an older cruiser, this three-way switch is an honest, no-drama way to manage your bilge pump. It does one job and does it well.

Frequently asked questions
What do the three switch positions do?
The switch has Auto, Manual, and Off. In Auto, the pump runs automatically when water rises in the bilge. Manual lets you run the pump on demand to clear the bilge yourself. Off keeps the pump from cycling, handy during storage or on the trailer.
Does it have a circuit breaker built in?
Yes. There's a 20-ampere circuit breaker built right into the switch, so you don't need a separate inline fuse for the pump. If the circuit draws too much current, the breaker trips and you simply reset it.
What voltage does this switch work with?
It's built for 12-volt DC systems, which is the standard on most bilge pump setups.
How do I know the pump is running?
The built-in LED indicator lights up when the pump is drawing power. One glance at your dash confirms the pump is doing its job without leaning over to listen for it.
Will it hold up in a saltwater environment?
The housing is made from corrosion-resistant ABS, so it stands up to the damp, salty conditions that wear out cheaper hardware.
What size bilge pump can I run through it?
Any standard 12-volt bilge pump whose current draw stays within the 20-ampere breaker rating. Check your pump's amp draw on its label and make sure it's under 20 amps.
