Abstract
A touchpad module includes a support member, a printed circuit board assembly (PCBA) and an elastic member. The support member has a protruding portion. The printed circuit board assembly is located over the support member and includes a capacitive sensing element corresponding to the protruding portion of the support member. The elastic member is disposed between the support member and the printed circuit board assembly. When the touchpad module is not pressed, a spacing between the capacitive sensing element and the protruding portion is smaller than a thickness of the elastic member.
