The Gems Series M level switch is a mechanical tilt float level switch designed for level control and alarm applications in difficult liquids such as sewage and waste water. The Series M utilizes a tether point—using either a tie-wrap or weight—which allows the switch to float within the pumping range.

Series M switches are free of any mercury and are housed in an impact and corrosion resistant ABS shell and utilize neoprene jacketed cable. The switches are available with either normally open or normally closed SPST contacts or with SPDT contacts with selectable normally open or normally closed (form C). Two pumping ranges are available: narrow angle which is 2 to 8 inches, and wide angle which is 5 to 18 inches.

Applications for the Gems Series M Level Switch:

  • Level Control
  • Alarms
  • Sewage Lift Systems
  • Slurries
  • Drainage Sumps
  • Wastewater Treatment
  • Holding Tanks
