Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A touch module includes an upper plate, a lower plate, a hinge structure, an elastomer and a touchpad assembly. The touchpad assembly is located over the upper plate. A first end of the upper plate and a first end of the lower plate are pivotally coupled to each other through the hinge structure. While the touchpad assembly is pressed down, a second end of the upper plate is swung downwardly relative to a second end of the lower plate and a switch element of the touchpad assembly is triggered. When the touchpad assembly is no longer pressed, the elastomer provides an elastic force to the upper plate. In response to the elastic force, the second end of the upper plate is swung upwardly relative to the second end of the lower plate and the touchpad assembly is returned to an original position.

Abstract: A keyboard device includes a base plate with a base plate with a connecting bracket, a wing-type connecting element and a keycap. A first connecting shaft of the wing-type connecting element is inserted into the connecting bracket, so that the wing-type connecting element is connected with the base plate. While the keycap is depressed, the first connecting shaft is inserted into a first receiving space of the connecting shaft and used as a swinging fulcrum. Since the vertical movement of the wing-type connecting element is restricted by the first receiving space, the swinging range of the wing-type connecting element is reduced. Consequently, the keyboard device of the present invention is capable of improving the depressing stability of the keycap.
