Description
The Daikin-McQuay 910103141 Pressure Switch is a differential control component used to monitor system airflow or refrigerant-side pressure conditions and provide safety or operational cut-in/cut-out control in HVAC systems. It responds to pressure changes within the equipment and sends an electrical signal to the control circuit to help regulate operation or protect system components from abnormal conditions such as loss of airflow or restricted flow. This switch is commonly installed in air conditioning and heat pump systems, where it integrates into the control and safety circuit assembly to support proper system sequencing fault protection, and reliable operation during heating.
