Description
The Trane SWT4131 pressure switch senses system opens or closes electrical contacts when pressure reaches the 1.60-inch water column setpoint, providing the safety control or operational sequencing in HVAC systems. It features a dilator element that responds to pressure changes, actuating snap-action contacts to interrupt or complete control circuits. It works in air handling systems, furnaces, or ventilation equipment where pressure differential monitoring ensures proper airflow operations. The fixed setpoint delivers consistent switching performance while its durable construction resists cycling. This pressure switch delivers stable pressure-based control when system safety depends on accurate pressure monitoring.
