摘要： A photoelectric switch key is provided, which includes a shell, a circuit board, a photosensitive component and a press component. The photosensitive component is electrically connected to the circuit board, and the press component is provided with a light-shielding member. The press component is movably mounted on the shell to enable the light-shielding member to move relative to a light-receiving surface of the photosensitive component. The photosensitive component is capable of receiving external light when the light-shielding member is moved away from the light-receiving surface of the photosensitive component. The light-shielding member is adjacent to and shielding the light-receiving surface of the photosensitive component when the press component is pressed. The light-shielding member is enabled to completely block the external light from irradiating on the photosensitive component when the key is pressed by the user, which achieves the function of the key, and improves the sensitivity of the key.

摘要： A floating trampoline-style keyboard structure, comprising a keyboard panel, a PCB board, and a keyboard base. The keyboard base includes a housing chamber. The PCB board is accommodated within the keyboard base cover and has a first gap with the bottom surface of the keyboard base cover. The keyboard panel is located above the PCB board and closes the opening, and the PCB board and the keyboard panel have a second gap. Several first avoidance holes are provided on the keyboard panel, and several second avoidance holes are provided on the PCB board. A plurality of limit screws are inserted into the first and second avoidance holes in sequence and then locked at the bottom surface of the keyboard base, which restricts the keyboard panel and PCB board from axially disengaging from the keyboard base.

摘要： An electronic device has a keyboard with an internal membrane. The membrane has a set of strain gauges configured to respond to a key press, such as when a collapsible dome collapses into contact with the membrane. The strain gauges are connected in a half Wheatstone bridge configuration and are positioned on the membrane in order to limit effects of temperature and subtle flexure of the membrane. The strain gauges are also configured to magnify detection of a resistance differential when a keycap is pressed with sufficient force.

摘要： A keyboard (110) includes a base board (116), keys (112), pitfalls (120) and a mode control mechanism (118). The keys (112) include cups (1124), and the mode control mechanism (118) may switch the keyboard (110) especially the key cups (1124) between different modes. In case that the keyboard (110) is not in use, these cups (1124) can be received in the pitfalls (120) to reduce the profile of the keyboard (110). In case that the keyboard (110) is to be used, the keys (112) may be raised up and arranged on the base board (116) in order to enable long keystroke and provide good typing experience.

摘要： A tactile-adjustable keyboard includes plural keyswitches, an adjustment frame and a hybrid operation button. The adjustment frame is disposed corresponding to the keyswitches to move and interfere at least one of the keyswitches. The hybrid operation button includes a tactile switch, a non-tactile knob disposed at least partially surrounding the tactile switch, and a lens disposed at least partially surrounding the non-tactile knob. The tactile switch includes a switch shaft and a switch bar. The switch shaft is disposed in rotatable connection with the adjustment frame to move the adjustment frame. The switch bar extends externally from the switch shaft. A tactile feedback of said one keyswitch changes in response to the rotation of the tactile switch, while a non-tactile signal is generated in response to the rotation of the non-tactile knob, and the lens is illuminated in response to the rotation of the tactile switch.
