However, the known elastic member has a certain height, so that the button needs to have a large height to accommodate the elastic member. In other words, the conventional buttons are provided with elastic members, so that the size of the button combination can no longer be reduced, which is not conducive to the thinning trend of the notebook computer. The key combination technology using magnetic parts has been applied to the production of some key products, and the related prior art can refer to U.S. Patent 4,453,148. [New Content] Therefore, one of the purposes of the present invention is to provide a button that utilizes magnetic attraction force as a driving force required for resetting a keycap to solve the above problem.

A key combination includes a top and bottom movable keycap having a space; a metal support plate having a hole, the metal support plate including a bridge column and a bridge surface; and a switch 'below the hole of the support plate a magnetic element placed in the space of the keycap; wherein 'when the keycap is unstressed, the keycap is in an initial state and the key combination is in an off state (OFF), the magnetic element Adsorption - on the bridge deck, when the keycap is subjected to a force downward, the magnetic element actuates the film to open #OFF' to make the button combination in an ON state (When the force is released, due to the magnetic component The magnetic attraction with the bridge deck returns the keycap to the initial state. The switch is a membrane switch. Using the key combination described above, the present invention is a keyboard that includes such a key combination. The keyboard includes a plurality of such key combinations. Other detailed features and details of the present invention are apparent from the description of the following embodiments and the scope of the claims. [Embodiment] Referring to FIG. 1A, the present invention includes a keycap 100 that can move up and down, the bottom surface of which has a space 102; a metal support plate 1〇4 having a hole 106' The metal support plate 1〇4 includes a cantilever bridge ;8; a switch 109 is located below the hole 1〇6 of the support plate 1〇4; a magnetic element 107′ is placed in the space 丨〇2 of the keycap . When the keycap is not stressed, the cap 100 is in an initial state (as shown in FIG. 1B) and the key combination 1〇 is in an off state (OFF). The magnetic element 1〇7 is attracted to the cantilever bridge 1 〇8, when the keycap 1〇〇 is subjected to a downward force, the magnetic element 1〇7 activates the switch 1〇9 to make the button group port 10 in an on state (〇N). When the applied force is released, the magnetic force between the magnetic element 107 and the cantilever bridge 〇8 will automatically return the keycap 丄(9) to M423855 ΐ (|αΐ2Γ〇9 Supplement, revision date: 2011.12.9 The keycap 100 has a pivoting portion 100a for pivotally connecting the support plate 104. The switch 109 can be a single-layer printed circuit board switch, a double-layer membrane switch or three. Figure 1B is a vertical diagram of the button group shown in Figure 1A (when the switch is open), that is, no external force is applied at this time. Because of the suction between the magnetic element 1〇7 and the cantilever bridge 1〇8, The key cap 1〇〇 naturally moves up to an upper stop point. At this time, the switch 1〇9 is in an off state. Fig. 1C is a diagram of the key combination group shown in Fig. 1A (when the switch is turned on), that is, at this time An external force is applied to the keycap 1〇〇. This external force needs to resist the magnetic attraction between the magnetic element 107 and the cantilever bridge 1〇8, so that the keycap 1〇〇 can be moved downward to the next stop point, and the current stop point. Upon arrival, the switch 1〇9 is energized by the magnetic element 1〇7. If the key is lost, the state of the key combination 1〇〇 is changed from FIG. 1C to FIG. 1B. In another embodiment 10 of FIG. 2A, a key combination 2 includes a top and bottom movable keycap 200 having a space. 2〇2; a metal support plate 2〇4 having a hole, the metal support plate 204 includes a bridge column 2〇8a and a bridge surface 208b; a switch 209 under the hole of the support plate 204; a magnetic element 207 It is placed in the space 2〇2 of the keycap 200. When the keycap 2 is not stressed, the keycap 200 is in an initial state (as shown in Fig. 2B) and the key combination 2〇 is in the off state. (OFF), the magnetic element 207 is attracted to the bridge surface 2〇8b. When the keycap 200 is subjected to a downward force, the magnetic element 2〇7 actuates the switch 2〇9 to make the button assembly 200 in an on state. (ΟΝ) β When the force is released, the magnetic force of the magnetic element 2〇7 and the bridge surface 208b causes the keycap 2〇〇 to move upward to return to the initial state. Fig. 2B is a view of Fig. 2A. The key combination group diagram (when the switch is open), that is, no external force is applied at this time, because the magnetic element 2〇7 and the bridge surface 2〇8a Force, the key cap 200 naturally moves up to an upper stop point, at this time, the switch 209 is in an off state. Fig. 2C is a diagram of the key combination group shown in Fig. 2A (when the switch is turned on). M423855 . At this time, an external force is applied to the keycap 200.
