A touchpad module includes a circuit board and a switch assembly. The switch element includes a conductive element and a metal dome. The conductive element is capable of providing buffering efficacy. The conductive element is arranged between the circuit board and the metal dome. When the metal dome is subjected to deformation, the metal dome does not collide with the circuit board to generate the click sound directly. Consequently, the comfort of operating the touchpad module is enhanced. The present invention further provides a computing device with the touchpad module.

A touchpad module includes a circuit board, a switch and a conductive raised structure. The circuit board includes a first conducting part and a second conducting part. The switch is installed on the circuit board. The switch includes a metal dome. The metal dome includes a first portion corresponding to the first conducting part and a second portion corresponding to the second conducting part. When the metal dome is subjected to deformation, the first portion of the metal dome is contacted with the first conducting part. The conductive raised structure is arranged between the second conducting part and the second portion of the metal dome. Since a gap is formed between the circuit board and the second portion of the metal dome, the contact area between the metal dome and the circuit board is reduced. Consequently, the generated noise is reduced.

A surface mount device switch includes a pedestal, a flexible conducting element and a metal dome. The flexible conducting element is connected with the pedestal. There is a spacing distance between the flexible conducting element and a circuit board. The metal dome is located under a pedestal conducting part of the pedestal and the flexible conducting element. When the flexible conducting element is pushed by the metal dome, the flexible conducting element is deformable in the direction toward the circuit board. Since the collision between the metal dome and the flexible conducting element is alleviated, the noise is reduced. Consequently, the comfort of operating the touchpad module is enhanced. The present invention further provides a touchpad module and a computing device with the surface mount device switch.
