[0064] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0065] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “” used herein may also indicate the inclusion of the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated, unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0066] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0067] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may also be rotated 90 degrees or in other orientations, and the spatial relative descriptors used in the text will be interpreted accordingly.

[0068] Existing rotary switches offer limited flexibility in adjusting the number of positions. The spacing and number of positions are fixed during production for most products, making it difficult to adapt to the specific needs of different equipment and increasing product development and production costs. Furthermore, the assembly structure of existing switches is complex, requiring high precision in the fit between components, significantly increasing the difficulty of the manufacturing process.

[0069] like Figures 1 to 14 As shown, according to an embodiment of the first aspect of the present invention, a multi-position rotary switch is provided, including an upper cover 1, a middle cover 2, a shaft 6, a limiting turntable 3, a spring 8, a ball bearing 9, a knob, and a potentiometer 4. The first side of the middle cover 2 is connected to the upper cover 1. The potentiometer 4 is disposed inside the middle cover 2. The limiting turntable 3 is rotatably connected to the upper cover 1. The middle cover 2 has multiple position holes 202 arranged in a circumferential array. One end of the spring 8 is inserted into the limiting turntable 3. The ball bearing 9 is connected to the other end of the spring 8. The first end of the shaft 6 passes through the upper cover 1, the limiting turntable 3, and the middle cover 2 in sequence and is then inserted into the potentiometer 4. The knob is connected to the second end of the shaft 6. During operation, the ball bearing 9 engages with one of the position holes 202, and the shaft 6 can drive the limiting turntable 3 to rotate.

[0070] In the above embodiments, it should be noted that a retaining ring 16 and a connecting screw 17 are also included. The retaining ring 16 is disposed inside the limiting turntable 3 and sleeved on the shaft 6. The lower cover 15, the middle cover 2, and the upper cover 1 are connected by the connecting screw 17. The edge of each gear hole 202 is arc-shaped. There are two balls 9 and two springs 8. One end of each spring 8 is inserted into the limiting turntable 3, and each ball 9 is connected to the other end of a spring 8. The number of gear holes 202 can be 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12.

[0071] The technical effects achieved by the above embodiment are as follows: This switch achieves the following through the cooperative arrangement of spring 8, ball bearing 9, and the circumferential array of gear position holes 202 in the middle cover 2: During operation, the ball bearing 9 engages with the gear position holes 202. With the elastic force of spring 8, the hard friction of existing slot-paddle structures is avoided, and a uniform damping feel is provided during rotational adjustment, making the switch rotation and adjustment process smoother without any jamming or sticking. Simultaneously, the positioning of each gear position hole 202 makes the gear shift feel more distinct, allowing users to judge the gear switching status by touch, effectively improving operational comfort and accuracy.

[0072] This switch integrates potentiometer 4 into the middle cover 2, and shaft 6 is directly connected to potentiometer 4. Different voltage values ​​are output through the linear change of resistance of potentiometer 4, which solves the problem of magnetic field interference. This allows the switch to effectively avoid signal fluctuations even in complex electromagnetic environments, ensure stable output voltage, and guarantee the reliability of electronic equipment.

[0073] In summary, this switch achieves smooth rotation, good feel and clear gear selection during gear shifting through the combination of multiple gear holes 202, spring 8 and ball bearing 9. In addition, the linear change of resistance of potentiometer 4 outputs different voltage values, which makes the switch more resistant to magnetic field interference and ensures the reliability of operation.

[0110] The working principle of this switch is as follows: when there are 12 gear position holes 202, when the gear position needs to be adjusted, simply turn the knob. The rotation of the knob drives the shaft 6 to rotate, which in turn drives the limit turntable 3 to rotate, which in turn drives the spring 8 and the ball 9 to engage the ball 9 with the corresponding gear position hole 202. At this time, the rotation of the shaft 6 adjusts the resistance of the potentiometer 4 to achieve the gear position adjustment.

[0111] When the number of gears needs to be adjusted, simply insert the positioning pin 502 into the corresponding gear socket 104. Since the positioning pin 502 works in conjunction with the second inner stop 304 and the first inner stop 306 works in conjunction with the upper and lower limits of the limit stop 204, the number of gears can be adjusted arbitrarily to 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12, to meet the user's different needs for the number of gears.

[0112] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
