This invention relates to a method for toggling between operation modes of a touch control device, being applied in an electronic data processing device with a touch control device and providing an electronic data processing device capable of toggling its operation between a first coordinate operation mode and a second coordinate operation mode to use the input of the touch control device, which comprises the steps of: setting a predetermined area of a touch control device as a switching mode area by a controller; determining a received position signal by the controller whether or not to act as an instruction for toggling its operation between the first coordinate operation mode and the second coordinate operation; and setting the current operation mode to another operation mode by the controller if the determination is true.
