The polarity of two adjacent magnetic units 3211 is different, that is, the polarity of one magnetic unit 3211 is S-pole, and the polarity of the other magnetic unit 3211 adjacent to it is N-pole. Because the polarity of the magnetic units 3211 is different, the generated magnetic field is different. By sliding the knob body 310, the Hall element 3221 detects the change of the magnetic field generated by the magnetic units 3211, and then triggers the corresponding signal to realize the switching of the corresponding function. The principle of realizing the key function by detecting the change of the magnetic field by the Hall element 3221 can refer to the common Hall switch products on the market, which is not limited herein. In an embodiment, the two adjacent magnetic units 3211 can be single-pole magnets, or two magnets can be attracted together to form different polarities at both ends, which is not limited herein.

In specific applications, the optimal selection can be made according to the actual situation, which is not limited herein.

[0039] In the embodiments of the present application, the first stop portion 331 is spaced apart from each other along the sliding direction, and there are at least two first stop portions 331 and at least one second stop portion 332. At least one of the at least two first stop portions 331 cooperates with the at least one second stop portion 332. In this way, the user can feel good when the signal switching position is switched, and the convenience of use is improved. In an embodiment, there are two or more first stop portions 331 and one or more second stop portions 332. When there are two or more first stop portions 331 and one second stop portion 332, one of the first stop portions 331 cooperates with the second stop portion 332 by sliding the knob body 310. When there are two first stop portions 331 and two second stop portions 332, one of the first stop portions 331 cooperates with one of the second stop portions 332 by sliding the knob body 310.

[0040] In the embodiments of the present application, referring to FIGS. 2-4, the first stop portion 331 includes a groove, and the second stop portion 332 includes an elastic member 3321.

[0041] In an embodiment, during the sliding of the knob body 310, the elastic member 3321 is compressed and deformed, and has elasticity. When the knob body 310 slides to a predetermined position, the elastic member 3321 returns to its original shape under the action of elasticity and is clamped into the groove, so that the user feels a hand feeling, thereby facilitating the user to identify that the knob body 310 has been slid to the predetermined position. In addition, in order to reduce the friction of the knob body 310 during sliding, a rolling member 3322 is arranged at the end of the elastic member 3321. The rolling member 3322 and the knob body 310 are in rolling connection, so that the sliding friction of the knob body 310 and the elastic member 3321 is converted into rolling friction, thereby effectively reducing the friction and improving the smoothness of the sliding of the knob body 310. In an embodiment, the rolling member 3322 can be a ball, a roller, etc., which is not limited herein.

[0042] In other embodiments of the present application, referring to FIG. 7, the first stop portion 331 comprises a first magnet 3311, and the second stop portion 332 comprises a second magnet 3323, the first magnet 3311 is provided with at least one, the second magnet 3323 is provided with at least two, the first magnet 3311 is arranged between the two second magnets 3323, and one of the at least two second magnets 3323 is adsorbed together with the at least one first magnet 3311.
