PROBLEM TO BE SOLVED: To provide a multi-function control key, which prevents from itself to make any functional error between different functions each, decreases the number of components of the multi-function key, and increases a number of control functions for the function key. SOLUTION: The multi-function control key, which may decrease the number of the components of the key and may increase the number of the control functions, is configured with a key disk and an elastic base uniting each other, comprises the functions of; executing the control function located at a central position of the key by using a central convex pillar; executing a driving function around the central position of the key by using a driving pillar located around the elastic base; inclining the central convex pillar located at the center of the key disk to various angles when an around central position of the key is driven; and, on the contrary, exerting the force on the key disk by touching to the central position of the key without generating any error at the center position since a downward moving distance for around the central position can be absorbed by the distance between a pillar body and a driving pillar, no driving error for around the central position is generated.
