Application

This pressure switch is intended for use in York-branded HVAC and refrigeration equipment where high-side refrigerant pressure monitoring is required. It serves as a critical safety device, interrupting the control circuit when refrigerant pressure exceeds the 650 PSI threshold and automatically resetting when pressure drops back to 450 PSI. Always verify compatibility with your specific York unit model before installation.
