For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] This utility model provides a reference. Figs. 1-5 In this embodiment of the utility model, a novel integrated magnetic shaft switch includes: an upper cover 4, a base 9, a button 1, a spring 8, a magnet 2, a circuit board 5, a magnetic induction switch 6, and an elastic connector 7.

[0025] The upper cover 4 and the base 9 fit together to form the outer shell structure of the shaft. The upper cover 4 and the base 9 can be connected together by means of snap-fit ​​connection, threaded connection or plastic welding.

[0026] Both the magnetic induction switch 6 and the elastic connector 7 are soldered onto the circuit board 5. The circuit board 5 is installed inside the shaft body and fits tightly with and is fixed to the upper cover 4. The pins of the magnetic induction switch 6 are connected to the elastic connector 7 through the lines on the circuit board 5. The elastic connector 7 is located at the lower end of the circuit board 5. The elastic contact 71 of the elastic connector 7 extends downward and is elastically connected to the PCB board A of the keyboard. This enables signal transmission between the magnetic induction switch 6 and the PCB board A of the keyboard.

[0028] The magnet 2 is arranged at the lower end of the guide column of the button 1, when the button 1 is pressed, the magnet 2 moves with the button 1, the distance between the magnet 2 and the magnetic induction switch 6 changes, thereby triggering the magnetic induction switch 6, transmitting a signal to the PCB board A of the keyboard, and realizing the input effect of the keyboard corresponding to the button 1;

[0029] The traditional magnetic shaft keyboard changes the way of installing the magnetic induction switch 6 on the PCB board A of the keyboard, and integrates the magnetic induction switch 6 on the circuit board 5 inside the shaft body, and is elastically connected with the PCB board A of the keyboard through the elastic connecting piece 7 (to avoid rigid contact), to realize the stability of signal transmission and structural compactness; at the same time, the relative position accuracy of the sensor and the magnet 2 is ensured, the displacement deviation caused by external vibration or pressing is avoided, and a structural basis for high-precision detection is provided.

[0030] Further, the lower end of the magnet 2 is provided with the pad 3, and the pad 3 covers the bottom surface of the magnet 2 to replace the contact between the magnet 2 and the base 9.

[0031] In actual use, the user can select the practical scene with or without the pad 3 according to different use scenes;

[0032] The pad 3 has the following functions: the pad 3 (the material can be selected from plastic, metal, silica gel, etc.) is sleeved on the magnet 2, the bottom of the pad 3 supports the magnet 2 and replaces the collision between the magnet 2 and the base 9, which not only protects the magnet 2 from being worn (extends the service life) but also realizes different collision sound effects through the diversification of the shape of the pad 3 (circular, conical, annular, etc.), thereby improving the user experience.

[0033] The pad 3 is compatible with the scene without the pad 3: the possibility of direct contact between the magnet 2 and the base 9 (when pressed to the bottom) is reserved, the confirmation feeling of the traditional magnetic shaft is considered, and the flexible switching between the "soft elastic structure" and the "traditional hand feeling" is realized.

Thus, for example, reference to "a component" can include a combination of two or more components, and the term "an element" can include comparable reference to a plurality of elements. Additionally, the term "or" as used herein means any one member of a logical disjunction (i.e., it is equivalent to "or" and "or else") and not a logical exclusion. Also, the terms "comprise," "comprising," "include," "including," and the like mean "including but not limited to." Furthermore, the description herein uses terms such as first and second to denote different elements, but the applicants do not intend these terms to denote an ordering, because some of these elements can, in fact, precede other ones in some of the implementations.

[0035] The above description of disclosed embodiments provides examples, and is not intended to be limiting. Numerous modifications of the embodiments, as defined herein, will be apparent to those in the art, and will not depart from the spirit or scope of the application.
