York S1-024-25329-706 Pressure Switch Els PW 17895 High-voltage insulation prevents electrical leakage

High-voltage insulation prevents electrical leakage and ensures 100% of the energy reaches the igniter

While it can monitor circuits downstream of a VFD

it ensures that the 1/4-28 stem operation remains within factory specifications

This pre-packaged relay features 2 SPST normally open (N/O) contacts

This direct OEM replacement ensures robust electrical connectivity between the system controller and the compressor terminals

York S1-024-25329-706 Pressure Switch Els PW 17895 High-voltage insulation prevents electrical leakageThe York S1 024 25329 706 Pressure Switch is a mission critical safety component designed for precise monitoring of pressure differentials within residential and light commercial HVAC systems. This SPNO (Single Pole Normally Open) switch is factory calibrated to a 1. 6" WC setpoint, specifically engineered to close on fall. This ensures that the furnace inducer motor provides sufficient draft for safe combustion before allowing the ignition sequence
