Description
The Rheem-Ruud AP24418 Pressure Switch is a pressure-actuated control component that responds to airflow or pressure variation within system lines. It opens or closes an electrical circuit at a defined pressure condition, allowing controlled signal transfer between connected components. HVAC systems across air handling and combustion-related assemblies use it to monitor pressure status during operational cycles. The switch interfaces with sensing tubing and control wiring to convert pressure changes into electrical response, supporting coordinated circuit activity within equipment assemblies used for airflow verification and system regulation in LOW-NOX configured burner setups.
