A control device for use in a cursor positing device is provided. The control device includes a housing, a control module, a sensing module and a circuit module. The housing defines an accommodation chamber. The control module is positioned on the housing and includes a movable member. The circuit module positioned within the accommodation chamber includes a microprocessor electrically coupled with the sensing module. The sensing module generates a first sensing signal in response to a first displacement variance in case of the first displacement variance achieved by moving the movable member in a major axis direction and transmits the first sensing signal to the microprocessor to reset the cursor to a first reset point.
