A surface mount device switch includes a pedestal, a metal dome and a conductive buffering sheet. A pedestal contact part of the pedestal is electrically connected with a circuit board. The conductive buffering sheet is arranged between the pedestal and the metal dome. Due to the conductive buffering sheet, the metal dome does not collide with the conducting part of the pedestal to generate the click sound. 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.

An electronic apparatus having a switch device capable of suppressing collision noise is disclosed. The switch device is equipped with a first fixed contact and a second fixed contact, and a metal dome that serves as a movable contact movable in a direction to be contacted with or separated from the first fixed contact. In a configuration in which the metal dome is moved to provide an electrical contact or a separation between the metal dome and the first fixed contact, whereby the first fixed contact and the second fixed contact are electrically connected therebetween, a conductive layer made of an anisotropic conductive sheet is provided between the first fixed contact and the metal dome.
