SWITCH

The MS24523-23 is a genuine Textron Aviation switch that controls an electrical circuit aboard the aircraft. It fits the 1900 Airliner, 1900C Airliner, 1900D Airliner, King Air 100, King Air 350 Fusion, King Air 350C FM-36 & On, King Air 350C Fusion, King Air 350i, King Air 360, and King Air 360C, among other compatible variants. It carries an export classification of ECCN EAR99. Because the MS24523-23 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer. Parts like this are shared across the Beechcraft 1900, King Air, and Premier aircraft, reflecting how much structure and hardware these models have in common. Ratings, tolerances, and interfaces are what define an electrical part; matching the specified item keeps the system working as certified. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger. Choosing the genuine article over an unapproved part keeps mechanics' sign-offs clean and the aircraft's configuration exactly as certificated. Built by Beechcraft — the Wichita, Kansas manufacturer founded in 1932 and part of Textron Aviation since 2014 — this part carries a name long associated with rugged, capable aircraft. Derived from the King Air, the 19-passenger Beechcraft 1900 airliner (built 1982–2002) remains in service with regional and cargo operators.
