FIG. 3 is a cross-sectional view of the button module in FIG. 2 along line B-B. Please refer to FIG. 1 to FIG. 3 , the button module 100 of this embodiment includes a housing 110 , a button 120 , a fixing member 130 and a switch element 140 . The side 112 of the casing 110 has a notch 114, the button 120 pivots relative to the casing 110 along the rotation axis A and is accommodated in the notch 114, the fixing member 130 is fixed in the casing 110 and is located below the button 120, the switch The component 140 is disposed in the housing 110 and located below the fixing member 130 . the

The button module 100 of this embodiment can be applied to a notebook computer. The casing 110 is, for example, the upper shell of the mainframe of the notebook computer, and the button 120 is a button adjacent to the touch panel 60 on the notebook computer host, wherein the touchpad 60 is for example It is disposed between the housing 110 and the fixing member, and is exposed by the slot 138 of the fixing member 130 in FIG. 2 and the slot 118 of the housing 110 in FIG. 1 . Please refer to FIG. 2 and FIG. 3 , the fixing member 130 of this embodiment has an opening 132 through which the button 120 can contact the switch element 140 . When the user wants to operate the button 120, he can push the button 120 sideways along the direction D1 shown in FIG. The button 120 is rotated relative to the casing 110 along the rotation axis A and contacts the switch element 140 through the opening 132 . the

It is worth noting that the button 120 of this embodiment is pivotally arranged on the casing 110, and the button 120 can be rotated relative to the casing 110 to contact the switch element 140 by pressing in various directions.
