What is meant by Cut-In and Cut-Out settings?

The cut-in and cut-out settings of a pressure switch are the PSI settings at which the switch starts and stops the pump.

Cut-In: a.k.a. “Reset Point” (falling pressure)

snap-action closes the contacts (completes the electrical circuit) pump starts

Cut-Out: a.k.a. “Trip Point” (rising pressure)

snap-action opens the contacts (breaks the electrical circuit) pump stops
