Float Switches


We supply float switches having 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 (inert gas contact), which is energized, through the non-magnetic walls of the float and guide tube, by the approach of the float magnet.
