Float Switch for Bilge Pump – 130 x 44 x 54 mm (Slim Design)

This 130x44x54 mm float switch features a slim, elongated design, allowing installation in places where other floats might not fit. For example, the bilges of certain speedboats or personal watercraft are very confined – this model addresses that issue by taking up minimal space. Despite its compact size, it fully performs its duty as an automatic switch: when water enters the compartment and rises to the trigger height, the float lifts and activates the pump. Once the pump drains the water down below a certain point, the float drops back and turns the pump off.

The unit is made of sturdy thermoplastic, resistant to prolonged submersion and the chemicals commonly found in marine environments. Its construction is designed to avoid sticking – the slim profile means it has less buoyant mass, resulting in quicker response to water level changes. The mounting holes and wiring leads are standard, so integrating it into an existing system or a new installation is straightforward.

When this slim float is most useful:

• Limited space: If your boat has a shallow bilge or very narrow compartments (e.g. in performance speedboats, small sailboats, or jet skis), a standard float switch might catch on surfaces or not move freely. With only 44 mm width, this float fits into spaces where width is critical and can operate unobstructed.
• Crowded bilge: On boats with lots of equipment under the floor (accessories, piping, wiring), there may be no convenient spot for a regular float. The slim design allows you to install it between components or in smaller wells of the bilge, enabling pump automation without major rework.
• Replacing a troublesome float: If your current float often sticks or fails due to spatial constraints, switching to this model could solve the problem. It’s compatible with the electrical parameters of standard bilge systems and will likely fit in spots where the old one struggled.
• General use: Even though it’s designed for tight spots, this float can be used in normal situations as well – it offers the same functionality as standard models, so it’s suitable for any boat owner who prefers a more compact device.

In conclusion, the 130x44x54 mm float switch offers flexibility in installation without sacrificing performance. It’s a smart solution for modern boats where space is often at a premium. With this float, you ensure your bilge is automatically drained even in areas that used to be challenging for standard switches, adding an extra layer of protection to your vessel.
