SWITCH

The S3443-1-1 is a genuine Textron Aviation switch used to make or break an electrical circuit. It is applicable to the Skyhawk and Skylane. It carries an export classification of ECCN EAR99, weighs 0.06 lbs, and measures 1.75 (L) x 1.3 (W) x 0.75 (H) in. Because the S3443-1-1 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. Across the Cessna Skyhawk and Skylane fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Ratings, tolerances, and interfaces are what define an electrical part; matching the specified item keeps the system working as certified. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. Using the factory part number preserves configuration control, so the airframe stays consistent with its approved type design and the work is straightforward to sign off at inspection. The Cessna name is among the most recognized in aviation — founded in Wichita, Kansas in 1927 and part of Textron since 1992, today a cornerstone of Textron Aviation. The Cessna 172 Skyhawk is the most-produced aircraft in history, with more than 44,000 built since 1956, and remains in production under Textron Aviation.
