The WIKA float switch is simple to mount and maintenance-free, so the costs of mounting, commissioning and operation are low. A float with a permanent magnet moves reliably along with the liquid level on a guide tube. Within the guide tube is fitted a reed contact, which is energised, through the non-magnetic walls of the float and guide tube, by the approach of the float magnet. By using a magnet and reed contact the switching operation is non-contact, free from wear and needs no power supply.

Large range of application due to the simple, proven functional principle
For harsh operating conditions and long service life
