FLOAT TYPE Switch Operation Depending on the mounting position, the float on these switches can either rise or lower with the liquid level. By rotating the switch 180°, the switch operation can be Normally Open or Normally Closed. Normally Open FLOAT ARC ENVELOPE 26° 26° When the switch is mounted so that the float lowers with the liquid level, the switch is N.O.
