A first potting waterproof part is formed by filling the first potting ring groove 113 with sealant and connecting the first potting ring groove 113 and the button ring plate 230. A second potting waterproof part is formed by filling the second potting ring groove 114 with sealant and connecting the second potting ring groove 114 and the lamp post ring plate 240. On the one hand, the nested arrangement makes the assembly of the button assembly 200 and the housing assembly 100 more stable. Furthermore, by setting the first potting ring groove 113 and the button ring plate 230, and the second potting groove and the lamp post ring plate 240, multiple layers of waterproofing are achieved. A first potting waterproofing section is connected between the first potting ring groove 113 and the button ring plate 230, and a second potting waterproofing section is connected between the second potting groove and the lamp post ring plate 240, preventing moisture from entering the receiving cavity 130 through the assembly gaps between the housing assembly 100 and the button assembly 200. This greatly improves the waterproof capability of the waterproof button assembly 10 and broadens its application scenarios.

[0044] like Figure 4 As shown, the side of the first housing 110 facing the receiving cavity 130 includes a first ring plate 115 surrounding the key hole 111 and a second ring plate 116 disposed outside the first ring plate 115, that is, located on the side of the first ring plate 115 away from the key hole 111.
