8406-025 OBSOLETE
- PRESSURE SWITCH C6052B1146
Bard part 8406-025 is an OEM pressure switch (manufacturer reference C6052B1146) used as a safety proving device in Bard wall-mounted HVAC equipment. It monitors system pressure conditions and changes state to confirm proper operation before allowing the unit to continue running, helping protect key components and prevent nuisance shutdowns when the correct switch is installed. Because pressure switch ratings and hose/port hookups vary by model and application, match 8406-025 to your unit’s specific Bard parts list and verify the pressure rating and electrical terminals on the original switch before ordering to ensure proper fit and reliable operation.
