Bard part number 8406-150 is an OEM magnetic reed switch with SPDT contacts used as a magnetic position or status input in Bard HVAC equipment, helping the control system prove conditions like access panel position or a magnet-actuated interlock signal. A reed switch is a sealed, magnet-operated electromechanical contact device, so correct mounting distance and wiring to the proper common and switched terminals is critical for reliable operation. If your unit is showing nuisance alarms, intermittent shutdowns, or missing a proven signal, replacing the switch with the correct Bard 8406-150 is the safest way to restore proper control logic and keep the unit operating as designed.
Please call for available options or find replacement parts.
