Abstract
A flexible potentiometer acts as a horn actuator in an automobile horn control system. In a preferred embodiment, the flexible potentiometer is adhered to a flexible substrate, which is in turn adhered to the inside surface of an airbag hub cover. The shape of the flexible potentiometer is chosen so that the automobile horn will sound when the driver presses against particular portions of the outside of the hub cover. The resistance of the flexible potentiometer changes as its shape changes as the user presses against the hub cover. A horn control circuit responds to extremely rapid changes in the resistance of the flexible potentiometer, but not to more gradual changes caused by, for example, temperature changes. Additional flexible potentiometers may be used to control other functions such as cruise control.
