Trane SWT2536 SPST Pressure Switch 2.10" WC

The Trane SWT2536 Pressure Switch designed for Trane HVAC applications in Single Pole and single Throw. Continuously monitors the air pressure of the system and is a safety device. It is an electromagnetic that opens or closes by a change in air pressure and it operates at a 2.10” water column pressure. That allows to control something like the start of the furnace blower when there is enough airflow or, on the contrary, shut down the system when there is too much pressure to harm components. The quick-connect terminal is 1/4 ” x 0.032” in size; this makes it easier to install.
