Amana-Goodman C6456513 SPST Pressure Switch -0.65" WC

The Amana-Goodman C6456513 is a single pole single throw pressure switch, which is used for detecting variations in pressure and taking action through sensing pressure in heating, ventilation and air conditioning systems. This pressure switch is designed to trigger at -0.65 inches of water column (WC). This means that the sensor is intended to pick up a very low pressure or negative pressure within the system. In practical terms, this type of switch is used to check the flow of air in the HVAC equipment and their venting.
