Actually it is a kick-down switch. According to the JTIS, to properly adjust it, the car should be connected to the computer and adjusted according to the reading on the computer at a certain throttle position. It has a wiring connector under the carpet that sometimes can cause the problem. If you have kick-down now, it probably is not to factory specs.

George, you are right. Some models have the switch under the gas pedal and some have only the stop under it (as has mine). Here is what the JTIS says :
Kickdown Switch (where fitted)
Kickdown is intended to provide maximum vehicle acceleration, via the appropriate downshift(s), when the operator uses full throttle. A kickdown switch provides an electrical signal to the TCM when the accelerator pedal is fully pressed. The switch is normally open, connected to vehicle ground. Should the switch fail the TCM will detect kickdown using the accelerator pedal position.
Throttle Pedal Stop (where fitted)
This component, used where the kickdown switch is not fitted, limits throttle pedal travel .in the same way. The kickdown feature is retained, but is controlled by throttle position only. The pedal stop must be set, using the PDU, in the same way as the kickdown switch to optimize performance.
