A dual-mode touch input apparatus, mounted in an electronic apparatus and capable of arbitrarily switching around a 1-D input mode and a 2-D input mode, comprises a touch pad, a flexible printed circuit board (FPCB) and a control chip. The FPCB is used for detecting a position of a user touch and issuing a detection signal to the control chip. The control chip is used for determining whether the dual-mode touch input apparatus is at the 1-D input mode or the 2-D input mode and producing a cursor signal in response to the user touch to control movement of a cursor on a screen of the electronic apparatus.
