PRODUCT DETAILS

FLOAT SWITCH 12V-24V-32V

Automatic Water Level Control for Bilge Pumps & Submersible Pumps

Keep unwanted water under control with the 12V/24V/32V Float Switch, a practical automatic water level switch designed for compatible DC bilge pumps and submersible water pumps.

Whether you're using it in a boat's bilge compartment or another suitable water collection area, this float switch automatically turns your pump on when the water rises and switches it off once the water level drops.

There's no need to manually monitor the water level or switch your pump on and off. The float switch responds to rising and falling water levels, helping prevent unnecessary water build-up.

Designed for 12V, 24V and 32V DC pump systems, this heavy-duty float switch is a convenient addition to suitable marine and low-voltage water pumping applications.

Why You'll Love It

  • Automatic Water Level Control: Switches your pump on and off according to the water level.

  • 12V, 24V & 32V DC Compatible: Suitable for a range of compatible low-voltage pump systems.

  • Automatic Pump Activation: Turns the pump on when the water reaches approximately 51 mm.

  • Automatic Pump Shut-Off: Switches the pump off when the water drops to approximately 19 mm.

  • Ideal for Bilge Pumps: Helps remove accumulated water from boat bilge compartments.

  • Heavy-Duty Design: Made for demanding water level control applications.

  • 1 Metre Cable: Supplied with a 1 m wire for electrical connection.

  • Simple Operation: Uses a floating mechanism to detect changes in water level.

  • Suitable for Submerged Use: Designed to operate in wet environments when correctly installed.

How Does the Float Switch Work?

The 12V/24V/32V Automatic Float Switch detects changes in water level and controls a compatible pump.

  1. Water Level Rises: Water collects around the float switch.

  2. Pump Switches On: When the water reaches approximately 51 mm, the float activates the connected pump.

  3. Water Is Pumped Away: The pump removes water from the collection area.

  4. Pump Switches Off: When the water level drops to approximately 19 mm, the float switch turns the pump off.

This automatic operation is particularly useful in boats, where water can accumulate in the bilge even when the vessel is not in use.

Ideal Applications

The float switch is suitable for a variety of compatible low-voltage water pumping systems, including:

  • Boat Bilge Pumps: Automatically remove accumulated water from bilge compartments.

  • Marine Water Removal Systems: Help control water levels in suitable boat compartments.

  • 12V DC Submersible Pumps: Provide automatic water level control for compatible pumps.

  • 24V DC Pump Systems: Suitable for compatible marine and water transfer installations.

  • 32V DC Pump Systems: Can be used with suitable 32V pumps within the switch's electrical ratings.

  • Small Water Collection Areas: Automate pumping where the installation and water levels are compatible.

A Practical Addition to Your Boat's Bilge System

Water can collect inside a boat for several reasons, including rainwater, splashes and small leaks.

A bilge pump float switch helps automate water removal by activating a compatible pump when water reaches the specified level.

This is especially useful when your boat is moored or left unattended, although the switch should not be relied upon as the only protection against flooding.

For dependable operation, the float must be able to move freely without being obstructed by cables, debris or nearby equipment.

Important Installation Information

  • Check Voltage Compatibility: Ensure your pump operates on a compatible 12V, 24V or 32V DC supply.

  • Do Not Exceed Current Ratings: The switch supports a maximum of 20A at 12V, 10A at 24V and 8A at 32V.

  • Use the Correct Fuse: Fit an appropriately rated fuse according to the pump manufacturer's requirements.

  • Waterproof Electrical Connections: All electrical connections must be properly sealed against moisture.

  • Keep Connections Above Water: Where possible, route wiring and position electrical joints above the expected water level.

  • Allow Free Movement: Install the switch where the float can rise and fall without obstruction.

  • Check Switching Heights: Ensure the 51 mm activation and 19 mm shut-off levels are suitable for your installation.

  • Test Before Use: Confirm that the float switch correctly activates and stops the connected pump.

  • Pump Not Included: This listing is for the float switch only.

Make water level management easier with the 12V/24V/32V Float Switch, a reliable and convenient solution for automatically controlling compatible bilge pumps and low-voltage submersible pumps.
