York S1-025-50188-000 Pressure Switch 328140-751 essential for maintaining stable headThe York S1 025 50188 000 is an OEM high pressure switch engineered for critical system protection in residential and commercial HVAC equipment. Traditionally found in R 410A systems, this normally closed switch monitors head pressure to prevent compressor damage and mechanical failure. It features a factory calibrated 650 PSI cut out threshold, which opens the electrical circuit when internal pressures exceed safe limits, and a 450 PSI cut in reset
