Float Switches

Float switches regulate the liquid level in tanks, wells, etc. and are used for automatic level control of groundwater, wastewater and sewage pumps, for raw water and liquid transfer pumps at waterworks, and for high water alarm.


What does a float switch consist of?


Float switches have a reed switch and a pivoted magnet and can be used for normally open (N/O) or normally closed (N/C) operation. The switch action can be reversed rotating the switch through 180°. The movement of float, due to changing fluid level, will cause the reed change to work (for instance close or open) at a specific level. This trusted and tried technology depends on a generally straightforward plan that offers long-haul quality without the requirement for the user to calibrate a switch.


What are material types of a float switch?


  • Nylon – used for oils, diesel, organic chemicals

  • Polypropylene (PP) – acids and alkali, detergents, oils, water, organic chemicals

  • Polyphenylene sulphide (PPS) – used for more aggressive chemicals, and higher temperatures, up to 120ºC

  • Stainless steel – medical and food industries, hydraulic fluids, chemicals

Features and Benefits


  • The highly flexible thermoplastic rubber cable has an extremely high mechanical load rating

  • The drop shape of the stabilizing weight eccentrically mounted in the housing makes the float switch insensitive to turbulence

  • The microswitch, fitted in a dual-chamber system, is completely shock- and rupture-proof

Where can be float switches used?


  • when emptying a tank

  • when filling a tank

  • for alarm at high water level

  • for alarm at low water level
