Normal Positions of Float Switches
A glass reed switch is hermetically sealed inside the stem from the liquid environment.
“Normal” float position means the fitting and wires are on top and the float is resting at the bottom of its travel range (not floating on liquid)
The changing level of the liquid moves the float up and down the stem.
Standard Vertical Fluid Switches can operate as Normally Open (NO) or Normally Closed (NC) by flipping the float 180° on the stem.
