Abstract
The utility model relates to a magnetic button combination. The magnetic button combination comprises a button cap, a support plate, a switch element and a frame body. The button cap comprises a fulcrum and rotates with the fulcrum as a shaft. The button cap further comprises a first magnetic element. The support plate which bears the fulcrum comprises a space for accommodating a second magnetic element. The second magnetic element and the first magnetic element are mutually repelling in terms of the polarity. The switch element is located below the button cap. When the button cap is not forced, the first magnetic element repels the second magnetic element so that the magnetic button combination is off. When the button cap is forced downwards and the repulsion force between the first magnetic element and the second magnetic element is overcome, the button cap moves downwards and makes the switch element actuated. By arranging the magnetic elements in the button combination, the button combination makes the overall thickness reduced and caters to the thinning trend of the notebook computer.
