Bard part 8406-138 is an OEM sealed SPDT lever switch rated for pilot duty service, used where Bard equipment needs a dependable mechanical position or interlock signal for control logic. This style of switch is commonly mounted on a bracket and actuated by a moving linkage or blade, helping confirm component position so the system can operate safely and consistently. Replacing a worn or intermittent switch with the correct Bard OEM 8406-138 helps restore proper unit sequencing and prevents nuisance faults caused by unreliable contact closure. Match the original wiring and mounting orientation, and verify operation against your Bard wiring diagram or parts list before returning the unit to service.
