York S1-024-27632-001 Pressure Switch Durable Construction: High-grade metalized polypropylene

Durable Construction: High-grade metalized polypropylene film encapsulated in an aluminum shell for maximum heat dissipation and dielectric strength

the high limit switch may be stuck open or tripped due to restricted airflow

the heater should be energized during the compressor's "off" cycle to maintain oil temperature

it maintains HVAC actuator compatibility across a wide ambient temperature range from -40°F to 150°F

York S1-024-27632-001 Pressure Switch Durable Construction: High-grade metalized polypropyleneThe York S1 024 27632 001 Pressure Switch is a critical safety component designed for specific HVAC pressure monitoring applications. This factory authorized part is engineered with a setpoint of 0. 4" WC (Water Column) and utilizes a Single Pole Normally Open (SPNO) internal contact configuration. Unlike standard switches, this unit is built to close on a fall in pressure, ensuring precise control and system protection during negative pressure
