Bard 8406-165BX - Filter Switch
The Bard 8406-165BX Filter Switch (boxed) is an OEM airflow proving and dirty filter safety switch used on select Bard wall mounted HVAC units to monitor filter loading and help protect the system from reduced airflow. When filter restriction rises beyond the set point, this switch can signal the control circuit to generate a service indication or initiate a protective response, helping prevent nuisance freeze ups and blower related strain caused by a clogged filter. If you are troubleshooting repeated filter alarms, low airflow faults, or you are replacing a failed or out of calibration filter switch, matching the Bard 8406-165BX to your unit model and control sequence is the best way to restore proper factory operation and reliable monitoring.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
