Cleveland Controls NS2-0221-00 SPDT Pressure Switch W/Mounting Bracket 1.35" WC

The Cleveland Controls NS2-0221-00 Pressure Switch W/Mounting Bracket responds to changes in pressure and transfers the sensed condition through an SPDT electrical contact arrangement. Its 1.35" WC rating indicates the specified pressure operating point, while the included mounting bracket provides the mechanical support needed at the installation position. Placed at the pressure-sensing point, the switch changes contact state in HVAC systems when the monitored pressure reaches the applicable threshold. The configuration provides a standard contact with normally open and normally closed switching paths for the connected control circuit. This pressure response supplies the required electrical signal for equipment sequencing.
