Abstract
The utility model relates to a magnetic key combination, comprising keycaps, support plates, switch elements and frames. Each keycap has a fulcrum, which is a rotating shaft of the keycap. In addition, each keycap has a first magnetic element. The support plates are used to bear the fulcrums. Each support plate has a space, in which a second magnetic element is embedded. The first and second magnetic elements are exclusive to each other in terms of polarity. The switch elements are located below the keycaps. When the keycaps are not forced, the first magnetic elements repel the second magnetic elements, so that the magnetic key combination is in an off state. When a downward press force applied to the keycaps exceeds a preset value, the keycaps move downwardly so as to actuate the switch elements. Through the arrangement of the magnetic elements in the key combination, the magnetic key combination of the utility model achieves a reduced integral thickness and caters the thin trend of laptops.
