Reznor 204328 SPDT Pressure Switch for HVAC Systems

The Reznor 204328 is a Single Pole Double Throw (SPDT) pressure switch designed for use in commercial and industrial HVAC heating systems. This critical safety component monitors air pressure within the system to ensure proper operation and prevent equipment damage.

Key Features:

• SPDT configuration provides versatile circuit control with dual output paths
• Precision pressure sensing mechanism for accurate detection and response
• Heavy-duty construction built for demanding commercial environments
• Automated pressure monitoring improves system safety and efficiency
• Compatible with Reznor gas-fired heaters and unit heating systems

This pressure switch plays a vital role in system operation by detecting pressure changes and triggering electrical contacts to control circuit flow. The SPDT design allows the switch to route signals from a common input to either of two outputs based on detected pressure conditions, making it ideal for applications requiring precise pressure-based control in heating systems.
