C292501-0109 – Textron Aviation Flap Selector Switch Kit
Available now on the Airparts.aero Marketplace.
The C292501-0109 is a genuine Textron Aviation (Cessna) OEM kit containing the flight-critical wing flap selector switch and its associated panel placard. This assembly is the pilot's primary interface with the electric flap system on a vast range of Cessna single-engine aircraft. Its function is to provide intuitive and reliable control over the extension and retraction of the wing flaps, a primary flight control during low-speed operations such as takeoff and landing.
The kit includes a high-quality, momentary three-position rocker switch, which is spring-loaded to a center-off position. This momentary action is a key safety feature, ensuring the powerful flap motor only runs while the pilot is actively commanding it. The switch is a Double-Pole, Double-Throw (DPDT) type, specifically designed to perform the polarity-reversing function required to drive the flap actuator motor in both directions. The reliability of this switch is paramount for safe and predictable operation of the flap system.
Key Features
Genuine Textron Aviation OEM Kit: Guarantees the correct switch type, electrical ratings, and a perfect fit in the instrument panel, including the correct placard.
Controls Flap Extension and Retraction: The primary pilot interface for commanding flap position.
Momentary (UP)-OFF-(DOWN) Rocker Switch: The spring-loaded-to-center design is a critical safety feature that prevents flap "runaway" in the event of pilot distraction.
Includes Position Annunciator Placard: The kit includes the precisely printed bezel that indicates flap positions (e.g., UP, 10°, 20°, 30°), ensuring a professional and compliant installation.
High-Reliability Electrical Contacts: The internal switch contacts are made from a silver-plated copper alloy, designed to handle the high inrush current of the DC flap motor without premature arcing or failure.

Why Choose C292501-0109?
Choosing the genuine Textron C292501-0109 is a critical decision for flight safety. The flap system is essential for safe takeoffs and landings. An intermittent or failed switch could leave a pilot unable to extend or retract flaps at a critical moment. Using a non-certified, generic switch from an electronics supplier introduces severe risks: it may not have the correct momentary action, its contacts may not be rated for the high inductive current of the flap motor, and its materials may not meet FAA fire-retardancy standards. The genuine Textron kit is the only way to guarantee a safe, reliable, and compliant repair to this flight-critical control system.
The flap switch in the C292501-0109 kit is a Double-Pole, Double-Throw (DPDT) switch, which is essential for its function as a DC motor polarity reverser. The six terminals on the back of the switch are wired in a reversing H-bridge configuration. In the center-off position, the flap motor is completely isolated from the electrical bus. When the pilot presses the rocker to the "DOWN" position, one set of poles connects the aircraft's positive DC voltage to the motor's "A" terminal and provides a path to ground for the "B" terminal, causing the motor to run in one direction. When the rocker is pressed to the "UP" position, the second set of poles makes the opposite connections: positive DC voltage is now connected to the motor's "B" terminal and ground is provided to the "A" terminal. This reversal of current flow through the motor's armature windings reverses the direction of the magnetic field interaction, thus reversing the motor's direction of rotation. The momentary action of the switch is a simple but critical safety feature, ensuring the powerful flap motor only runs while the pilot is actively holding the switch, preventing an unattended flap runaway condition.
Note: This is a flight-critical flight control component. An inoperative or intermittently functioning flap switch is unairworthy and must be repaired. All electrical work must be performed by a certified A&P or avionics technician in accordance with the Textron/Cessna maintenance and wiring diagram manuals. After installation, the flap system must be tested on the ground through its full range of motion to verify correct direction of travel, limit switch operation, and position indicator accuracy.
