A multi-direction input device for computers includes a direction wheel, a toggle mechanism and a plurality of electrodes. The direction wheel has one-degree of rotational freedom and two-degree of freedom to perform clicking, forward rolling, backward rolling, leftward moving and rightward moving operations. Thereby mating electrodes are electrically connected to generate corresponding signals. In normal conditions, the toggle mechanism and a movable contact jointly support the direction wheel. When the direction wheel is depressed, the toggle mechanism drives and connects a corresponding electrode to generate a click signal.
