    摘要： A key switch including a base section, a key top, a pair of link members and a switching mechanism. Each link member is provided, at one end region thereof, with a toothed portion meshable with a toothed portion of another link member in a gearing manner and a pivot axle pivotably joined to the base section, and at another end region, with a slide portion slidably engaged with the key top. The base section includes a support plate and a frame member, the frame member being fixedly attached to the upper surface of the support plate. The frame member is provided with a bearing portion pivotably receiving and supporting the pivot axle of each link member. The first end region of each link member is disposed on a lateral side of the frame member and closely to the upper surface of the support plate.

    摘要： A keyboard, wherein an opposing force generated between two magnet faces of the same polarity is used to return each key button to its original position after being pressed. As a result, the keyboard can be made capable of withstanding harsh environments whilst offering a satisfactory tactile response for the user.

    摘要： A key structure (100) which is adjustable in pressing force required and in duration of key pushback includes a circuit board (60), a keycap (10), a first magnetic member (20), an elastic member (30), a membrane switch (40), and a second magnetic member (50). The keycap includes a pressing portion (11) and an extending portion (12) connected with the pressing portion. The membrane switch is spaced apart from the first magnetic member, and the elastic member buffers the first magnetic member against the membrane switch. The second magnetic member is disposed between the membrane switch and the circuit board. When energized, the second magnetic member generates magnetic attraction or magnetic repulsion to the first magnetic member. A pressing force required on the key structure and a rebound force and a delay of rebound can be dynamically adjusted by direction and magnitude of a current applied to the second magnetic member. A key device (1) including the key structure is also disclosed.

    摘要： The present application provides a photoelectric switch key which includes a shell (10), a circuit board (20), a photosensitive component (30) and a press component (40). The photosensitive component (30) is electrically connected to the circuit board (20), and the press component (40) is provided with a light-shielding member (41). The press component (40) is movably mounted on the shell (10) to enable the light-shielding member (41) to move relative to a light-receiving surface of the photosensitive component (30). The photosensitive component (30) is capable of receiving external light when the light-shielding member (41) is moved away from the light-receiving surface of the photosensitive component (30). The light-shielding member (41) is adjacent to and shielding the light-receiving surface of the photosensitive component (30) when the press component (40) is pressed. The light-shielding member (41) 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. Moreover, it is unnecessary to arrange an additional pairs of infrared emission tube to supply a light source, and the structure is simple and compact, which is conducive to the development of key miniaturization.
