The driving mechanism 3 can drive the connecting sheet 21 to be connected with each terminal 22 to conduct each terminal 22, so that the communication of the circuit where the switch is located is realized; the driving mechanism 3 can also drive the connecting sheet 21 to separate from each terminal 22, so as to realize the disconnection of the circuit of the switch. The drive mechanism 3 can drive the connecting piece 21 by pressing.

Referring to fig. 2-4, the sound generating mechanism 4 includes a push block 41 and a sound generating component 42, the sound generating component 42 is connected to the casing 1 through a swing structure 43, and the sound generating component 42 is elastically connected to the casing 1. Through the elastic connection structure and the swing structure 43, the sounding component 42 is in the middle position in the natural state, and is not in contact with the shells 1 on the upper side and the lower side, and the sounding component 42 can swing under the action of external force. The pushing block 41 is arranged on the driving mechanism 3, and when the driving mechanism 3 presses and drives the connecting sheet 21, the pushing block 41 can be driven to push the sounding component 42 to swing at the same time, so that the sounding component 42 can collide with the shell 1 on the upper side and the lower side to generate sound when swinging, and the sounding function in the on-off process of switch control can be realized; moreover, the sound generating component 42 generates sound through impact of the swing and the shell, so that the swing amplitude of the sound generating component 42 can be controlled to be large, the size of the generated sound is improved, and enough sound stimulation is brought to a user.
