A Brief Guide for Using Float Switches


Float switches help in detecting the levels of liquid within the tank. The float switch is responsible for closing the circuit as soon as the liquid levels drop or rise.

Float switches for tanks use various features to ensure adequate maintenance of the levels of liquid. The features are often customizable as industries choose features that suit their production methods the best.


As mentioned above, the primary purpose of a float switch is to operate the circuits of a water tank. The two wires that come from the top of the switch are responsible for completing the circuit. The float switch takes help from a magnetic reed switch to complete the course. The current moves through the circuit once the magnets become attracted to one another. Similarly, the circuits break once the magnets move away from each other.

Tank level gauges responsible for indicating the levels of water inside the tank, use the float switches to measure the hydrostatic pressure inside the tank.

Magnetic Energy

The function of a float switch is heavily dependent on magnetic energy that is part of the system. Vertical float switches use a magnet that is part of the thru tube float, and the magnetic switch reed for passing the current through the system.

Float switches are a tried and trusted technology that has made a name for itself in the industry. The simple design and efficient performance are some of the significant reasons why industries are using these devices in various industrial production methods.

Apart from industrial methods, float switches come in handy for other purposes too. Everyday appliances such as the dishwater or the fish tank use the vertical float switch to manage the flow of water.
