Application

This pressure switch is commonly used in Trane gas furnaces and air handling units as a safety control device. It monitors the negative pressure created by the inducer motor to confirm adequate venting and combustion airflow before the ignition sequence proceeds. If pressure falls outside the calibrated setpoint range, the switch opens the control circuit, shutting down the system and preventing potentially hazardous operation.
