A keyswitch device includes a bottom plate, a keycap, and a position-returning member. The keycap includes a metal cover and a covering member. The metal cover includes a first main body. The first main body has a first surface and a second surface respectively facing toward and facing away from the bottom plate. The first surface presents a pattern. The covering member includes a second main body covering the first surface. The second main body has a light-transmitting area covering the pattern. The position-returning member is disposed between the bottom plate and the keycap and contacts the first main body.

Keyswitch device

A keyboard device includes a bottom plate, key caps, a circuit board, reset members, and assembly structures. The bottom plate has assembly regions. The key caps are above the bottom plate and correspond to the assembly regions. The circuit board is under the key caps. The key caps are abutted by the reset members. The assembly structures are between the bottom plate and the key caps. Each assembly structure includes an assembly member and a long rod. The assembly member is on the assembly region. The long rod is on the assembly member and is capable of moving up and down relative to the bottom plate. Each key cap includes a clamp portion. The clamp portion is on the long rod. The key cap is connected to the bottom plate via the clamp portion and is swingable about the long rod relative to the bottom plate.

Keyboard device

The present invention relates to a key structure and a keyboard having the same. The key structure includes a seat, a conductive membrane disposed on the seat, a scissor assembly, a light source, and a cap. The seat has a plurality of protruding hooking portions. At least one conducting section is defined on the conductive membrane away from the central portion thereof. The collapsible scissor assembly is arranged between the seat and the cap. The key structure has at least one protrusion arranged above the corresponding conducting section. A rubber element having a hole formed on the top portion thereof is disposed centrally on the conductive membrane. The light source is arranged beneath and covered by the rubber element. The cap is disposed on the scissor assembly. The protrusion may be arranged on the side portion of the scissor assembly or the undersurface of the cap.
