Float switch – liquid level switch – level sensor
Prevent your pump from running dry or overrunning your container with our float switches. This reliably monitors the liquid level in containers or water tanks. You get a signal (alarm) when it’s empty or filled. This automatically can switch your pump on or off, depending on the liquid level. So you can protect your pump from failure. Float switches are a cost-effective and maintenance-free alternative to expensive electronic sensors. Our level switches are very energy-saving as no permanent power supply is needed.
Float switches off the shelf will never exactly meet your requirements and desires.
These do not fit your application. Either you change your container or device, or you will find a manufacturer that will tailor the level switch to your needs .
We can help you here and that at standard prices. Our developers modify one of our numerous standard types or develop a completely new variant for you (OEM product).

Save time and money:
Float switch are available as standard products or customized variants.
However, for a standard product, the switching point, size or material composition is not aligned with your application. In order for your pump to turn on or off at the desired level, you need a sensor or switch that fulfills this requirements. A suitable material should be chosen for the level switch that is suitable for the medium used, such as water or oil. On choosing the wrong material, the float switch will not work after some time.
In most cases, you will only get the best results if you only adapt your requirements and your device.
Customize the float switch exactly to your requirements.
Depending on the used liquid, the case material and the float must be selected. This is crucial for the long-term functionality of the sensor. For agressive liquid you can use stainless steel or PE.
The temperature of the liquid also plays an important role here. You can use stainless steel for higher temperature.
Choose your prefered cable or wires type and your optimal length.
The right connector provides a fast and secure connection with the control or submersible pump. You should never switch a 230V pump directly as this destroys the float switch.
Choose your appropriate components. We are happy to support you in the optimal selection.
Float switches monitors the filling of a water tank. Mostely you will check if the tank is full or empty. However, other levels can also be monitored. This allows you to monitor the filling in more detail. Depending on the design, the float sensor has 1 or more switching points for the respective level to be detected. For this purpose, several floats are needed.
1 switching point
2 switching points
3 switching points
Our float switches operate according to the simple and durable principle of reed switch technology. The float lifts or lowers along a steep pipe depending on the level of fluid. The magnet in the float switches the reed contact inside the climbing tube without contact. Depending on the positioning of the magnet and reed switch, different switching points can be realized in order to recognize exactly your desired level. Float switches can have one or more switching points.
Compared to other techniques such as inductive, capacitive or ultrasonic, these require no permanent power supply and are very energy-saving. They can be used in almost any environment. Float switches are maintenance-free, durable and easy to assemble. This guarantees low installation and operating costs.
You can attach the level switch to different positions of your container or tank. We generally distinguish between vertical mounting and horizontal mounting.
By means of a thread at the float switch, it is screwed to the container.
