Detroit Radiant TP-264F Pressure Switch Els PW 17895 the TS194 is the replacementThe Detroit Radiant TP 264F Pressure Switch is an essential OEM replacement part designed for Re Verber Ray tube heaters. This differential pressure switch features a normally open (N O) configuration, serving as a critical safety interlock that monitors combustion airflow. For high output systems ranging from 150,000 to 200,000 BTU H, this component ensures the burner only fires when the blower achieves the required differential pressure set point.
