Float switch

Float switch SWS

With a floating VA/PVC float bulb, SWS serve as level detection, pump control, overflow protection and level indicator. In industry, float switches are used to detect the level of liquids. They operate independently of foam, conductivity, pressure, vacuum, temperature, vapours, condensate, bubbling and vibrations and are suitable for almost all liquid media. Contactless, wear-free switching without auxiliary power.
