Bard 910-2135BX is an OEM low pressure switch assembly supplied boxed, used in Bard wall mounted air conditioners and heat pumps to monitor refrigerant suction pressure and help protect the compressor by opening the control circuit if pressure drops out of the normal operating range. This safety switch is commonly tied into the unit control wiring to prevent operation under low charge or restricted airflow conditions, helping reduce nuisance freeze ups and long term compressor damage. For best results, match the part number exactly and confirm your unit model and wiring diagram before ordering, since switch settings and lead configurations can vary by series.
* Orders less than $50 may incure a minimum order fee.
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.
