Fanfare button
The button for the air horn is located in the center of the steering wheel. The air horn button is also referred to as the horn switch. Pressing the air horn button pushes the contact pins in the wheel's center pad against their contact surfaces in the steering wheel. This closes the circuit.
The air horns are available for operation at all switch positions starting with Terminal 15 ON.
