Abstract: A key structure includes a protective cover and a keycap. The keycap includes flow-guiding bevel surface. When the protective cover and the keycap are adhered on each other through a glue material, an excess portion of the glue material is retained on the flow-guiding bevel surface. Consequently, the excess portion of the glue material will not spread to other regions.

Abstract: A magnetic key includes a keycap, a base plate, a membrane circuit member, a frame, a first magnetic element, a second magnetic element, and a third magnetic element. The frame includes a first concave structure, a second concave structure and an opening. An accommodation space is defined by the frame and a first protrusion structure and a second protrusion structure of the base plate. The first magnetic element is received within the first concave structure. The second magnetic element is received within the second concave structure. The third magnetic element is disposed under the keycap and accommodated within the accommodation space. In response to a first magnetic force between the first and third magnetic elements and a second magnetic force between the second and third magnetic elements, the keycap is protruded out of the opening.

Abstract: A keyboard device includes a key structure, a switch circuit board, a base plate, a soft covering element and a buffering pad. The key structure includes a keycap and a stabilizer bar. The stabilizer bar is connected with the keycap and the soft covering element. The soft covering element is disposed on the base plate. An accommodation space is defined by the soft covering element and the base plate collaboratively. The stabilizer bar is inserted into the accommodation space, so that the stabilizer bar is connected with the base plate. The buffering pad is disposed on the base plate and partially received within the accommodation space. The stabilizer bar and the base plate are made of metallic material. Since the stabilizer bar and the base plate are separated by the soft covering element and the buffering pad, the keyboard device is capable of reducing noise.

Abstract: An illuminated keyboard includes at least one light-emitting element, a membrane switch circuit module, plural keys, a fixing plate, and a proximity sensor. The fixing plate includes plural openings, plural joining regions, and plural fixing regions. The plural fixing regions are arranged between the plural openings for fixing plural elastic elements of the plural keys. The proximity sensor includes an induction antenna circuit. The induction antenna circuit is formed on the plural joining regions or the plural fixing regions of the fixing plate for sensing whether an object enters a sensing range.

Abstract: A key structure includes a base plate, a switch circuit board, a keycap, and an enclosure frame. The keycap includes a magnetic element. The magnetic element is disposed on an edge part of the keycap. The enclosure frame includes a magnetic coating layer. The magnetic coating layer is formed on an edge part of the enclosure frame and disposed over the magnetic element. When the keycap is depressed, the keycap is moved to trigger the switch circuit board, so that the switch circuit board generates a key signal. When the keycap is no longer depressed, the keycap is moved toward the magnetic coating layer in response to the magnetic force. The key structure can be normally operated without the need of installing an elastic rubbery element.
