Nordyne 632493R SPST Pressure Switch 0.60" WC

The Nordyne 632493R SPST Pressure Switch is used to detect and react to the variation in the differential pressure in HVAC systems. Its main purpose is to open or close an electrical circuit when the pressure rises to the set 0.60 inches of water column. It works in such a way that it senses the change in pressure over an internal sensing element and then activates the contact. It consists of installing the unit in the specified pressure line and the electrical connection as specified.
