Vertical Float Switches
The magnetic float switch consists of non-abrasive float carrying permanent magnet and non-ferrous stem carrying one or two reed switches. The float glides along the stem and when the float nears the vicinity of reed switch the magnetic field of permanent magnet forces the reed contact to close, thereby completing the external electrical circuit.
Due to its simple design, reliability and with only one moving part i.e., magnetic float, it finds applications in various liquids where accurate and repeated liquid level control is called for.
However the float switches do not work satisfactorily in highly contaminated liquids and liquids with the high viscosity.
This type of float switches are suitable for centralized lubrication systems for machine tool, printing, packaging, packaging, textile and special purpose machines.
