◊ Reed Switch Type Float Level Switch


◈ Features

 • Compact construction
 • Top bottom or side mounting
 • Totally enclosed electric parts
 • Wide selection of switch functions and ratings
 • Easy maintenance
 • Stainless steel and plastic models

◈ Application
  Reed switch type float level switches are widely used for fresh water, sea water and low viscosoty liquids.

◈ Operating Principle
  This level switch have a magnet built in the float and a reed switch set inside the guide pipe.
  The reed switch is turned on and off with the up-and-down liquid levels. The two stopper located above and below, the float enable float shift range to limit, thereby providing a self-hold reed switch contact operation.
