SEAFLO Marine Bilge Pump Float Switch - 12-32V DC, 20A
The SEAFLO Marine Bilge Pump Float Switch is designed to control a compatible boat bilge pump in response to changing water levels. Intended for marine bilge-water management systems, this automatic bilge pump switch helps activate a connected pump when the water reaches the switch's specified operating level.
The supplied product information lists a 12-32V DC operating range, a 20A current rating, ignition-protection features, and 18 AWG wiring. Before installation, verify the electrical ratings, wiring configuration, mounting requirements, and compatibility with your selected bilge pump.
This product is a pump-control switch, not a complete bilge pump. Check the manufacturer's documentation to confirm the switching levels, approved installation locations, and included accessories before ordering.

How a Marine Bilge Pump Float Switch Works
A marine bilge pump float switch helps control a compatible pump according to the water level in the bilge. When the water reaches the switch's activation point, the switch changes state to control the connected pump. As the water level falls, the switch may return to its reset state according to its design.
The exact activation height, reset height, switching arrangement, and mounting orientation depend on the product. Follow the SEAFLO installation instructions rather than assuming specific operating levels.
Compatibility and Electrical Requirements
Before purchasing this automatic bilge pump switch, check the electrical and physical requirements of the connected pump and vessel.
- System voltage: Confirm that the vessel's DC supply falls within the switch's permitted voltage range.
- Pump current: Check operating and starting current against the switch's specified load rating and conditions.
- Wiring configuration: Follow the manufacturer's wiring diagram and confirm the required switching arrangement and circuit protection.
- Installation location: Verify the approved mounting position, available movement, and environmental limits.
- Ignition protection: If the switch will be installed where flammable vapors may be present, verify the applicable documentation and marine installation requirements.
A float switch does not increase the connected pump's flow capacity. Select a bilge pump appropriate for the vessel and ensure the complete control system is compatible with the installation.
Installation and Maintenance
- Disconnect the power supply before installing or servicing the switch.
- Follow the manufacturer's wiring diagram and electrical protection requirements.
- Mount the switch in the approved position and ensure its movement is not obstructed.
- Keep the switch and surrounding bilge area clear of debris that could interfere with operation.
- Inspect wiring, terminals, and connections periodically for damage, looseness, or corrosion.
- Test the switch and connected pump according to the manufacturer's recommended procedure.
- Do not exceed the specified voltage or permitted switching load.
- Consult a qualified marine electrician if you are unsure about wiring, circuit protection, or installation requirements.
Important: Verify the switch's electrical rating, ignition-protection documentation, and installation suitability before use. A float switch is only one component of a bilge-water management system and does not replace regular inspection or maintenance.
Frequently Asked Questions
What is a marine bilge pump float switch used for?
It controls a compatible bilge pump in response to water-level changes, helping automate pump operation without requiring manual activation for every cycle.
Is this a complete bilge pump?
No. This product is a float switch for controlling a compatible bilge pump. Check the selected package contents and confirm whether additional wiring or control components are required.
Is the switch compatible with 12V and 24V systems?
The supplied product information lists a 12-32V DC range, which includes nominal 12V and 24V DC systems. Confirm the permitted operating range and installation requirements in the manufacturer's documentation before connecting it.
What does the 20A rating mean?
The product listing specifies a 20A rating. The permitted load depends on the manufacturer's rating conditions and the type of electrical load. Verify the connected pump's operating and starting current before use.
Is this float switch ignition protected?
The product is advertised as ignition protected. Verify the manufacturer's supporting documentation and applicable marine electrical requirements before installing it in a compartment where flammable vapors may be present.
Does it work with every bilge pump?
Not necessarily. Compatibility depends on voltage, current draw, wiring configuration, switching requirements, mounting space, and the pump manufacturer's instructions.
Can I install the switch myself?
Installation must follow the manufacturer's wiring diagram and applicable marine electrical requirements. If you are unfamiliar with bilge-pump wiring or ignition-protection requirements, consult a qualified marine electrician.
What should I check before ordering?
Confirm the voltage range, permitted current load, wire and connection requirements, activation and reset levels, mounting orientation, ignition-protection documentation, and package contents.
