York S1-024-34561-000 Pressure Switch 0.95" WC X 0.4" WC

The York S1-024-34561-000 is a dual-port pressure switch designed for HVAC applications. This pressure switch monitors differential pressure to ensure safe and proper operation of heating and cooling equipment.

Key Features:

• On pressure setting: 0.95 inches water column (WC)
• Off pressure setting: 0.4 inches water column (WC)
• Designed for use in York furnaces and HVAC systems
• Ensures proper draft and combustion air pressure monitoring
• Factory-calibrated for reliable, consistent operation
• Direct OEM replacement part for York equipment

This pressure switch is a critical safety component that detects pressure differentials in the system. When pressure reaches the set point, the switch closes to allow the heating cycle to continue. If proper pressure is not achieved, the switch prevents equipment operation to protect against unsafe conditions.
