Is the low pressure cut-off setting on a pressure switch adjustable?

The low pressure cutoff remains fixed at 10 psi below the low pressure cut-in setting for the
pressure switch. Although it is not independently adjustable, it will follow the low pressure
set point.

20-40 Switch Setting:    Low Pressure Cut-Off activated at approx. 10 PSI

30-50 Switch Setting:    Low Pressure Cut-Off activated at approx. 20 PSI

40-60 Switch Setting:    Low Pressure Cut-Off activated at approx. 30 PSI

NOTE: The pressure switch will not be effective if the cut-in point is set below 10 psi.
