Float switches

Float level switches for effortless level control

Float switches are highly effective at detecting point-based limit levels for one or more switch points. WIKA’s portfolio has a float switch for almost all liquid media and interfaces, regardless of foaming, conductivity, pressure, vacuum, temperature, vapors, condensation, boiling effects, turbulence, corrosion, or vibration. Because a float switch uses a free-moving magnet and potential-free reed contact, the switching operation requires no power supply and is not prone to wear and tear. WIKA manufactures vertical and horizontal float switches, mechanical float switches, bilge float switches, and more. Our level engineers can also custom-build solutions for your particular application.


How does a built-in magnetic system work?

A float with a built-in magnetic system moves with the level of the medium to be measured on a guide tube which has one or more reed switch contacts built into it. The magnet actuates the contacts at the pre-set switching heights and thus allows indi ...
