Supco SLP2565 Low Pressure Switch, 25 PSI Cut-Out, 65 PSI Cut-In, SPST

Description

The Supco SLP2565 is a dependable SPST low pressure switch engineered for refrigeration and HVAC system protection. Designed to open on pressure drop, this switch automatically interrupts the circuit when system pressure falls to the cut-out set point, safeguarding compressors and refrigeration equipment from the damaging effects of low-pressure conditions such as refrigerant loss or evaporator freeze-up.

How It Works

The SLP2565 monitors system pressure continuously. When pressure drops to the cut-out threshold, the switch opens (breaks the circuit), shutting down the system to prevent damage. Once pressure recovers to the cut-in set point, the switch closes and restores normal operation — providing automatic, pressure-driven protection without manual intervention.
