As shown in fig. 7, the first housing 1 has a cavity 11 open at both ends. Optionally, the first housing 1 is made of a light-transmitting material, and light emitted by the light emitting element on the circuit board 120 is transmitted out through the first housing 1.
The key 2 is slidably arranged in the cavity 11 of the first housing 1. The inner wall of the cavity 11 is provided with an annular limiting part 12. The length of the key 2 is greater than the length of the through hole in the limiting part 12, the width of the key 2 is greater than the width of the through hole in the limiting part 12, and the limiting part 12 plays a limiting role on the key 2 when the key 2 moves downwards to be in abutting connection with the limiting part 12.
The support 3 is slidably disposed in the cavity 11. The support 3 is connected with the key 2, for example, the support 3 is connected with the key 2 in a clamping manner. The electric control switch 140 is located below the support frame 3, the electric control switch 140 is abutted against the waterproof piece 130, the waterproof piece 130 is abutted against the support frame 3, and the elastic contact of the electric control switch 140 plays a supporting role on the support frame 3.
