Bard 910-1977BX - Overflow Switch Assembly
The Bard 910-1977BX Overflow Switch Assembly is an OEM condensate safety switch used on Bard wall-mount HVAC equipment to help protect the unit from water-related shutdowns and damage when the drain pan or condensate system backs up. When moisture rises to an abnormal level, this switch is designed to open the low-voltage safety circuit and stop operation so you can address the drainage issue before it becomes a leak, overflow, or indoor comfort problem. This is a boxed, factory-correct Bard replacement intended to match original wiring and mounting for proper fit and dependable safety operation, and it should always be verified against your unit model and parts manual before ordering.

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.
