In addition, this design also enhances the beauty of the button structure.

[0036] See also Figure 1 to Figure 6 A circular notch is provided on the button housing 2, and the end of the light guide 3 is fitted in the notch. The illuminated waterproof button structure can also include a light board 4 and lamp beads 6, wherein the light board 4 is fixed to the inner surface of the shell 1, and the button housing 2 is located between the shell 1 and the light board 4; the lamp beads 6 are all fixed on the side of the light board 4 facing the button housing 2 and facing the light guide 3.

[0037] When the waterproof button structure with light involved in the utility model is in use, the operator presses the button housing 2 to control the switch 5, and the switch 5 controls the on and off of the lamp beads 6 arranged on the light board 4. When the lamp beads 6 are in the on state, since the lamp beads 6 are facing the light guide 3, the light emitted by the lamp beads 6 will be transmitted through the light guide 3 and light up the button structure.

[0038] In this embodiment, when assembling the button structure, it is only necessary to connect the outer shell 1 and the light board 4 together. The button shell 2 fits into the mounting hole 101 and is clamped between the outer shell 1 and the light board 4.
