Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 7, the button switch described in this embodiment includes a key cap 1 and a lower cover 2, the lower cover 2 is provided with a receiving groove 21, the key cap 1 is disposed in a matching manner with respect to the receiving groove 21, the button switch further includes a balance bar 3, the key cap 1 is provided with a pivot hole 11, at least one slide rail position 23 is disposed in the receiving groove 21, one end of the balance bar 3 is rotatably connected to the pivot hole 11, the other end of the balance bar 3 is slidably connected to the slide rail position 23, when the key cap 1 is pressed, one end of the balance bar 3 rotates in the pivot hole 11, and the other end of the balance bar slides in the slide rail position 23, the key cap 1 of the present invention has good pressing balance, when the key cap 1 is pressed, the balance bar 3 realizes the mutual limiting position of the key cap 1 and the lower cover 2, even if the pressed position is not the middle position of the key cap 1, the balance bar 3 rotates in the pivot hole 11 on the key cap 1, according to the difference of stress points, the balance rod 3 slides in a downward pressing mode or an upward pulling mode in the sliding rail position 23, the position of the balance rod 3 relative to the lower cover 2 is balanced, and therefore the key cap 1 moving synchronously with the balance rod 3 is limited and guaranteed to move in a balanced mode.

In some specific embodiments, the accommodating groove 21 is provided with two stoppers 22 matched with the slide rail position 23, specifically, in this embodiment, the slide rail positions 23 are symmetrically provided with two stoppers 22 matched with the slide rail positions 23, and the first stopper 222 and the second stopper 223 are provided in the case that the stoppers 22 are matched with the slide rail positions 23.
