What Does a Bilge Pump Switch Do?
A bilge pump switch automatically turns your bilge pump on and off based on water level or moisture detection. It’s the key component in any automatic bilge pump system, ensuring your boat stays dry even when you’re not aboard.
- Float Switches: Use a buoyant lever to activate the pump when water rises.
- Electronic Switches: Use moisture sensors for more accurate and maintenance-free operation.
- Panel Switches: Provide manual/auto/off control from your dash or helm.
Popular Bilge Pump Switch Options
| Switch Type | Best For | Key Features |

How to Choose the Right Bilge Pump Switch
- Boat Size: Larger boats may need multiple switches or higher-current rated models.
- Environment: Choose sealed electronic sensors for oily or debris-heavy bilges.
- Current Rating: Match your switch’s amp capacity to your bilge pump’s draw (usually 10–20A).
- Mounting: Side-mount for deep bilges; vertical-mount for confined spaces.
Pro Tip
For a complete bilge system, pair your bilge pump switch with a compatible automatic bilge pump and add hoses and check valves for safe discharge. Many boaters also install manual bilge pumps as emergency backups.

Frequently Asked Questions
How do I wire a bilge pump switch?
Connect the switch inline between your bilge pump and 12V power source using marine-grade wire and waterproof connectors. Follow ABYC color-coding and fuse your circuit correctly.
Can I use any switch with any bilge pump?
No — match your switch’s amp rating and voltage to your bilge pump’s specifications. Most switches are rated for 12V systems up to 20 amps.
What’s better: float or electronic switch?
Float switches are cost-effective and proven, while electronic switches offer maintenance-free operation and resist debris buildup.
Should I have both automatic and manual control?
Yes — a manual/auto/off panel gives you flexibility to override the automatic system or shut it off when servicing your bilge pump.
