BSK-S
Sync and Switching Unit
Description
BSK-S synchronization and switching unit
BSK-S is an aircraft synchronization and switching unit. Aviation inventories also expand the Cyrillic БСК-С designation as a synchronization-and-control block or a communication-and-switching block. These descriptions consistently identify an avionics interface function, but they do not establish a universal pinout or a complete aircraft effectivity list.

BSK-S role in onboard electronics
The unit belongs to the signal-coordination layer of aircraft avionics. Its role is to synchronize, control or switch signals between cooperating blocks according to the installed system logic. It must not be confused with the unrelated BSK-1 industrial power-coding unit or with BSK-4 and BSK (1612) course-synchronization blocks.
Documented aircraft context
BSK-S appears in documented MiG-29 aviation-equipment inventories together with BSR-31, BP-20 power units and other blocks of the onboard electronic complex. This confirms an aircraft application, but the available record does not identify the exact subsystem execution. Consequently, MiG-29 is recorded as context rather than unrestricted effectivity.
Identification and compatibility
Selection requires the complete Cyrillic nameplate БСК-С, any drawing or assembly number, connector keying and the system designation from the aircraft records. BSK-S, BSK-M, BSK-4 and BSK (1612) are different products. Similar abbreviations must not be merged, and no electrical values should be copied from those other units.
Inspection and ordering
Inspect the housing, rack fittings, connectors, seals and markings before testing. A functional check requires the correct system diagram and test procedure because the open sources do not provide a verified terminal assignment. State the full marking, aircraft and subsystem, quantity, condition and documentation requirements in the enquiry. Related units are under Electronic Control Units.
