Nordyne 632499R WC SPST Pressure Switch - 0.60

The Nordyne 632499R is a single-pole single-throw (SPST) pressure switch designed for HVAC applications. This pressure switch is calibrated to activate at -0.60 inches water column (WC), making it ideal for monitoring negative pressure conditions in furnaces and heating systems.

Key Features:

• SPST switching configuration for simple on/off control
• -0.60" WC pressure activation point for precise pressure monitoring
• Genuine Nordyne OEM replacement part ensures proper fit and function
• Designed for residential and light commercial HVAC equipment
• Direct replacement for failed or malfunctioning pressure switches

This pressure switch is a critical safety component that monitors the pressure differential in the venting system. When proper pressure is achieved, the switch closes to allow the heating sequence to continue. If insufficient draft is detected, the switch remains open to prevent unsafe operation.
