A keyswitch includes a board, a cap opposite to the board, a first support device, a second support device, and a first link member. The first support device is disposed between the cap and the board. An end of the first support device is connected to the board. Another end of the first support device is connected to the cap. The second support device is disposed between the cap and the board and is separate from the first support device at a specific distance. An end of the second support device is connected to the board. Another end of the second support device is connected to the cap. The first link member has a first end portion and a second end portion. The first end portion is movably connected to the first support device. The second end portion is connected to the second support device.

A key structure includes a keycap, a pedestal and an elastic element. The keycap includes a main body and a coupling shaft. The pedestal includes a key slot. The key slot has an upper part and a lower part. The coupling shaft is penetrated through the upper part of the key slot and movable within the key slot upwardly or downwardly. The elastic element is installed in the lower part of the key slot. After an external force applied to the keycap is released, the elastic element is elastically restored, so that the keycap is returned to an original position. At the same time, the buffering elements in the key slot interfere with the coupling shaft. Consequently, an ascending speed of the keycap is reduced, and a click sound generated from the collision between keycap and the pedestal is reduced.

The disclosure provides a keyboard includes a bottom plate, a key unit and a shielding layer. The bottom plate includes a body part and a through hole. The key unit is disposed on the body part. The shielding layer covers a portion of the bottom plate and comprising a main part disposed on the body part and an extension part extending from the main part toward the through hole, wherein the extension part has a hole with a size larger than or substantially equal to a size of the through hole.

An electronic watch may include a tactile switch and/or one or more sensors for detecting rotational and translational inputs. The watch may include a display configured to produce graphical outputs that may change in response to rotational inputs, translational inputs, and/or touch inputs received at the display. The watch include a crown positioned along an exterior of the watch enclosure and a shaft coupled to the crown and extending into the enclosure. The tactile switch and/or the one or more sensors may be used to detect rotational and/or translational inputs provided at the crown.

A keyswitch structure includes a base plate, a keycap, and two supports connected to the base plate and the keycap. The keycap is movable relative to the base plate through the two supports. The support is pivotally connected to the base plate through a pivotal connection structure that includes a guiding slot and a protruding shaft oppositely disposed on the support and the base plate. The guiding slot has an opening and an indentation portion. The opening is located at an upper end of the guiding slot. The protruding shaft enters the guiding slot from the opening to rotatably fit in the indentation portion, so that the support is pivotally connected to the base plate.

A key module includes a keycap, an indicator light source, a first backlight source and a second backlight source. The keycap includes an indication area and a character area. The indicator light source is configured to emit an indicating light of a first color toward the indication area. The first backlight source is configured to emit a first backlight of the first color toward the character area. The second backlight source is configured to emit a second backlight of a second color toward the character area, wherein the second color is different from the first color. As a result, the key module could display the light of different colors based on different operations, thereby being distinguishable from the color of the light emitted by the adjacent key module.

A touchpad module includes a bracket, a touch member and a supporting assembly. The touch member is located over the bracket. The touch member includes a membrane wiring board and a circuit board. The circuit board is located over the membrane wiring board. The supporting assembly is arranged between a second end of the touch member and the bracket. While a first end of the touch member is pressed down, the first end of the touch member is swung relative to the bracket. Consequently, a membrane switch of the membrane wiring board is triggered. The present invention further provides a computing device with the touchpad module.

A keyswitch device includes a cap, a board, a first returning member, and a second returning member. The board is disposed opposite to the cap. The first returning member is disposed between the cap and the board and includes a magnet member and a magnetic member for providing a magnetic force. The second returning member is disposed between the cap and the board for providing an elastic force. When the cap is released at a lowest position, the cap moves upward via the elastic member and then arrives and stays at a highest position via the magnetic force.

A detachable screen key structure mainly includes a key body having a hollow portion, key butting element and screen carrying element, where a key signal connecter is configured in the hollow portion, the screen carrying element is configured with a display element and a key cap is configured on the display element, and the display element is configured with a display butting element adapted to dock the key butting element. Whereby, a user can accommodate the key signal connecter for signal transmission inside the hollow portion so as to increase use beautification. Furthermore, since the display will be connected to the key butting element through the display butting element, the user is allowed to carry out the removal and replacement by themselves, which can increase use convenience.
