York S1-024-35283-000 -0.35″wc SPST Pressure Switch, 1/4″ Barbed

Description

The York S1-024-35283-000 is an OEM replacement SPST (Single-Pole, Single-Throw) pressure switch engineered for precise, reliable pressure sensing in York HVAC systems. Designed to open or close a circuit at a specific negative pressure set point, this switch helps protect equipment from unsafe operating conditions such as blocked flue passages or inducer motor failures.

Key Features

• OEM York replacement pressure switch for verified system compatibility
• Set point: -0.35″ water column (wc) — factory-calibrated for accurate trip performance
• SPST (Single-Pole, Single-Throw) switching action for straightforward circuit control
• 1/4″ barbed port connection for secure, leak-free hose attachment
• Compact, durable construction designed to withstand demanding HVAC operating environments
• Direct drop-in replacement minimizes installation time and complexity

Application

This pressure switch is commonly used in York gas furnaces and air handlers to monitor inducer/draft blower operation. When the correct negative pressure is not achieved — indicating a venting or inducer issue — the switch prevents the ignition sequence from proceeding, protecting both the equipment and the occupants.
