The melted filler overflowing from the first surrounding edge 33 of the first protective piece 30 is isolated by the tearable piece 50a from flowing to the outer key 42 area of the switch module 41. The key type of the key 42 includes but is not limited to a pot piece key.

[0032] Please refer toFigure 1 、 Figure 5 and Figure 6 After the cooling forming, the shell 10, the first protective member 30 and the key function module 40 are formed as a one-piece whole. The tearable member 50a is removed from the switch module 41; then the key 42 of the switch module 41 capable of normal triggering is exposed. Understandably, assuming that the first protective member 30 does not exist, please refer to Figure 7 , only need to set the tearable member 50a in the area of the key 42 outside the switch module 41, and remove the tearable member 50a after the shell 10 is formed, the normal triggering of the key 42 of the switch module 41 can also be protected.

[0033] Further, please refer to Figure 1 、 Figure 3 and Figure 4 , the protective shell 100 further comprises a second protective member 50; the second protective member 50 is mounted to the first protective member 30 from the outside of the shell 10. Preferably, the second protective member 50 is detachably mounted to the first protective member 30. In the protective shell 100 equipped with the second protective member 50, it can be understood that a receiving space 60 for accommodating the switch module 41 is formed between the first protective member 30 and the second protective member 50. In this way, the finished protective shell 100 ensures the normal triggering of the key 42 of the switch module 41 through the second protective member 50 mounted to the first protective member 30.

[0034] Specifically, the second protective member 50 has a key hole 52. The key 42 is exposed from the key hole 52 of the second protective member 50; in this way, the key 42 can be normally triggered on the outside of the protective shell 100.

[0035] Further, the key 42 comprises a key cap 45 and an outer edge 46 extending from the edge of the key cap 45. The key cap 45 is limited by the key hole 52, and the outer edge 46 is limited between the first protective member 30 and the second protective member 50.
