SWITCH

The MS24659-21A is a genuine Textron Aviation switch used to make or break an electrical circuit. It fits the Beechjet 400/400A, Citation III, VI or VII, King Air 350 Fusion, King Air 350C FM-36 & On, King Air 350C Fusion, King Air 350i, King Air 360, King Air 360C, King Air B200, B200T, B200C or B200CT, and King Air B200GT, among other compatible variants. It carries an export classification of ECCN 9A991. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS24659-21A meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Across the Beechcraft, Cessna Citation, and Beechcraft King Air fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. In an aircraft's electrical system, using the correct component preserves the circuit's designed behavior, reliability, and safety. Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Both the Cessna and Beechcraft lines are supported today by Textron Aviation, formed in 2014 to unite the two historic Wichita manufacturers with Hawker. The Beechjet 400, which began life as the Mitsubishi Diamond and later became the Hawker 400, is a light business jet supported today through Textron Aviation.
