FIG. 1 and FIG. 2 are respectively a schematic diagram of the appearance of a button device 50 having a waterproof function according to an embodiment of the present invention, and FIG. 4 is a schematic view of the components. FIG. 3 and FIG. 4 are respectively the present invention. A schematic cross-sectional view of the embodiment of the button device 50 in different states. The button device 50 can be used to input a switching signal. For example, the button device 50 can be a power switch button device. The button device 50 includes a button housing 52, a button body 54 and at least one resilient member 56. The inside of the button housing 52 is formed with a hollow chamber 521; the button body 54 is movably mounted in the hollow chamber 521 of the button housing 52, and the button body 54 is formed with at least one groove 541. A gap G is formed between an outer edge 543 of the button body 54 and an inner wall 523 of the button housing 52. The elastic members 56 are respectively mounted in the corresponding grooves 541 of the button body 54 and are used to close the button body 54. The gap G between the outer edge 543 and the inner wall 523 of the button housing 52, wherein the elastic member 56 can be an annular elastic member, such as a soft material such as silicone or rubber, and the groove 541 can be a ring. The groove is disposed around the outer edge 543 of the button body 54 and the annular elastic member is sleeved in the annular groove to closely fit the elastic member 56 into the groove 541. In the embodiment, the button body 54 is formed with two grooves 541, and the button device 50 includes two elastic members 56 respectively mounted in the two grooves 541 of the button body 54, and the groove 541 and the elastic member. The combination manner, setting position and number of 56 may not be limited to those described in this embodiment, depending on actual design requirements.

When the user presses the button body 54 of the button device 50 in a first direction (+X direction) to switch the button device 50 from the state of FIG. 3 to the state of FIG. 4, the elastic members 56 are opposed to each other. The button housing 52 moves. It should be noted that each of the grooves 541 can be a beveled structure, and the width of each of the grooves 541 is gradually increased in the first direction (+X direction), so when the button body 54 is in the first direction ( When the +X direction is moved relative to the button housing 52, each of the elastic members 56 is movable relative to the ramp structure, thereby being elastically pressed by the button body 54. Since each elastic member 56 can close the gap G between the button body 54 and the button housing 52, the pressure between the two elastic members 56 can be designed to be greater than the external atmospheric pressure, and the relative distance between the two elastic members 56 is maintained constant.
