These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0067] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present application.

[0068] The positional nouns such as “upper”, “lower”, “lateral” and the like involved in the embodiments of the present application are generally based on the assembled state of the switch, and these positional nouns are only used to more clearly describe the structure and the relationship between the structures, and are not intended to describe absolute positions. Among them, the position of the button of the switch is taken as “upper” or “top”, and the position of the base of the switch is taken as “lower” or “bottom”. When the product is placed in different postures, the positions may change, for example, “upper” and “lower” may be interchanged.

[0069] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below in conjunction with the drawings.

[0070] The small-angle switch provided by the related art has a driving member arranged between the button and the transition piece, the button rigidly drives the driving member to rotate, the rotating driving member in turn drives the transition piece to rotate, and finally the rocker is actuated, and the rotation stroke of the button is amplified. However, this makes the actuation of the button feel heavy, and is prone to abnormal sound of the switch shaking and the like.

[0071] In view of the technical problems existing in the related art, the embodiments of the present application provide a switch, as shown in Figure 1 , attached Figure 2 and attached Figure 3As shown, the switch comprises a seat body assembly 1, a pressing piece 2, one or more groups of switch units, and the switch unit comprises a button 3, a driving piece 4, a transition piece 5 and a switch function assembly 6. The driving piece 4 comprises a driving body part 41 and a first driving part 42 and a second driving part 43 respectively located at both ends of the driving body part 41.

[0072] The number of switch units can be one group, two groups or more than two groups, for example, three groups, four groups, five groups, six groups, etc. The one or more groups of switch units share the seat body assembly 1 and the pressing piece 2. When the number of switch units is more than one group, the corresponding switch is a multi-position switch.

[0073] For the button 3 of the switch unit, the button 3 has two pressing sides, one of which is always up when the switch is in the off state, and the other pressing side of the button 3 is down when the switch is in the off state. When it is necessary to switch the switch between the off state and the on state, the up pressing side of the button 3 can be pressed.

[0074] Referring to Figure 2 and Figure 3 , the assembly relationship of the above-mentioned components in the switch is as follows:

[0075] The pressing piece 2 and the switch function assembly 6 are located inside the seat body assembly 1, the button 3 is hinged to the seat body assembly 1, the first end of the transition piece 5 is hinged to the pressing piece 2, the second end of the transition piece 5 penetrates the pressing piece 2 and acts on the switch function assembly 6, and the two driving pieces 4 are symmetrically arranged on both sides of the transition piece 5. The driving body part 41 is hinged to the pressing piece 2, and the first driving part 42 is hinged to the corresponding side of the first end of the transition piece 5. Among them, the side of the transition piece 5 hinged to the first driving part 42 is the swing side, and the two swing sides are respectively located on the opposite sides of the first end of the transition piece 5.

[0076] The distribution direction of the two driving pieces 4 is consistent with the distribution direction of the two pressing sides of the button 3, and the pressing driving force of the button 3 is transmitted to the transition piece 5 through the driving piece 4, so as to achieve the purpose that the rotation angle of the button 3 is less than the rotation angle of the transition piece 5.

[0077] In particular, at least one of the second driving part 43 and the button 3 has a resilient structure, so that the second driving part 43 and the button 3 are in elastic abutment; wherein the resilient structure is configured to be stretchable in a direction perpendicular to the button 3.

[0078] In the following description, the pressing side of the button 3 that is up in the off state of the switch is referred to as the first pressing side, and the other pressing side that is down in the off state of the switch is referred to as the second pressing side.

[0079] In one aspect, the switch provided by the embodiment of the present application can amplify the rotation angle of the button 3, which is beneficial to the design of the small swing angle of the button 3. The small swing angle working principle of the switch provided by the embodiment of the present application will be described below by way of example: Figure 3

[0080] When the switch is switched from the off state to the on state, the first pressing side of the button 3 is pressed, and the button 3 rotates in the counterclockwise direction. Since the second driving part 43 elastically abuts against the driving rib 31 of the button 3 and the driving body part 41 is hinged to the pressing piece 2, the driving piece 4 corresponding to the first pressing side rotates counterclockwise. Since the first driving part 42 of the driving piece 4 is hinged to the corresponding side of the first end of the transition piece 5, the driving piece 4 rotates while driving the corresponding side of the transition piece 5 to swing upward, so that the transition piece 5 rotates in the clockwise direction. The lower end of the transition piece 5 rotating in the clockwise direction acts on the switch function assembly 6, so that the switch function assembly 6 is switched from the off state to the on state, realizing the switch from the off state to the on state.

[0081] At the same time, the rotating transition piece 5 drives another driving piece 4 corresponding to the second pressing side to rotate counterclockwise synchronously, and finally, the second pressing side of the button 3 is switched from the drooping state to the upwarping state when the switch is switched to the on state.

[0082] It can be seen that by arranging the driving pieces 4 between the button 3 and the transition piece 5, the two driving pieces 4 are hinged to the two sides of the transition piece 5, and the driving pieces 4 work in the manner of a lever, based on the lever amplification principle, the rotation of the button 3 is amplified and transmitted to the transition piece 5, so that the button 3 can drive the transition piece 5 to obtain a larger rotation angle with a smaller rotation angle, which plays a role in amplifying the rotation angle of the button 3. Since the rotation angle of the button 3 is smaller than the rotation angle of the transition piece 5, under the condition that the depth of the fixing frame 13 and the rotation stroke of the transition piece 5 are unchanged, the pressing stroke of the button 3 can be effectively reduced to improve the hand feeling, and the thickness of the switch can be correspondingly reduced to improve the flatness and aesthetics of the product, so that the switch can be designed as an ultra-thin switch.

[0083] In addition, the hinged connection between the transition piece 5 and the driving piece 4 also helps to reduce the friction loss between them.

[0084] ​In another aspect, the switch provided by the embodiments of the present application can reduce the pressing feeling of the button 3 and effectively avoid the problem of abnormal sound caused by the switch shaking. This is because the elastic structure arranged in at least one of the second driving part 43 and the button 3 can be stretched and contracted in the direction perpendicular to the button 3, so that the second driving part 43 and the button 3 are elastically abutted. In this way, when the button 3 and the second driving part 43 of the driving member 4 interact, the elastic structure is compressed to have a certain buffering and rebounding effect, so as to ensure that the button 3 and the driving member 4 are always closely abutted, which can effectively avoid the problem of abnormal sound caused by the switch shaking. Further, since the elastic structure is compressed to exert a certain elastic force on the button 3, this is beneficial to reducing the pressing force of the button 3, so that the pressing feeling of the button 3 is lighter.

[0085] The second driving part 43 and the button 3 are elastically abutted by the elastic structure. The elastic structure can be arranged on the second driving part 43, or can be arranged on the corresponding position of the button 3, or can be arranged on both. The elastic structure can be stretched and contracted in the up-down direction perpendicular to the button 3. In the assembled state of the switch, the elastic structure is in a preliminary compressed state. Hereinafter, the arrangement of the elastic structure is described by way of example:

[0086] In some examples, the elastic structure can be arranged on the second driving part 43, as shown in FIGS. 11 to 13. Figure 4 Figure 5 Figure 6 As shown in FIGS. 11 to 13, the second driving part 43 includes: a rigid arm 431 and an elastic arm 432 arranged side by side; wherein the distribution direction of the rigid arm 431 and the elastic arm 432 is perpendicular to the distribution direction of the two pressing sides of the button 3, so that the rigid arm 431 and the elastic arm 432 can be simultaneously driven by the button 3.

[0087] The abutment end of the elastic arm 432 is higher than the abutment end of the rigid arm 431, so that the abutment end of the elastic arm 432 abuts against the button 3 earlier than the abutment end of the rigid arm 431. That is, the surface of the abutment end of the elastic arm 432 facing the button 3 is higher than the surface of the abutment end of the rigid arm 431 facing the button 3, which can be defined as the upper surface.

[0088] During the assembly of the button 3, the button 3 first contacts the elastic arm 432. When the assembly of the button 3 is completed and the switch is in the assembled state, the elastic arm 432 is compressed to have a certain elastic force, which can effectively solve the problem of abnormal sound caused by the switch shaking.

[0089] ​​When the button 3 is pressed downward, the elastic arm 432 continues to be compressed until the elastic arm 432 is compressed to be flush with the upper surface of the rigid arm 431, the driving of the button 3 is in contact with the elastic arm 432 and the rigid arm 431 at the same time, the elastic arm 432 reaches the maximum compression stroke, at this time the elastic arm 432 has the maximum elastic force, so that the dialing force value of the panel is reduced, and the panel has a lighter dialing feeling.

[0090] In addition, due to the elastic force of the elastic arm 432, the button 3 is always in contact with the driving piece 4 during dialing, which can also reduce the false position phenomenon of the button 3 caused by the instantaneous bounce of the flap 62, and improve the user experience of the switch.

[0091] In some examples, referring to Figure 5 and Figure 6 , the elastic arm 432 includes: an elastic arm segment 4321 and a first abutting end 4322; one end of the elastic arm segment 4321 is connected to the driving body part 41, the other end of the elastic arm segment 4321 is connected to the first abutting end 4322, and the first abutting end 4322 is used to abut against the button 3.

[0092] The elastic arm segment 4321 is arranged in a suspended manner, and has elasticity to stretch and contract in a direction perpendicular to the button 3. Of course, on this basis, the length, thickness and width of the elastic arm segment 4321 can be further adjusted to adjust the elastic effect of the elastic arm segment 4321.

[0093] The elastic arm segment 4321 can be a straight arm or a bent arm, wherein the bent arm has better elasticity and has greater elastic force when compressed.

[0094] For example, Figure 6 The elastic arm segment 4321 is in a bent shape. For the bent elastic arm 432, the bent structure can be an arc-shaped bend or a linear bend. For example, an arc-shaped bend structure can be used, which is beneficial to reduce the stress at the bend and improve the structural stability and service life of the elastic arm segment 4321.

[0095] In some examples, one, two or more bend structures can be provided on the elastic arm 432 in the length direction thereof. For example, Figure 6 The elastic arm 432 is provided with two bend structures in the length direction thereof, one of which is convex upward, and the other of which is concave downward and closer to the first abutting end 4322.

[0096] The first abutting end 4322 is used to abut against the button 3. In some examples, as shown in the accompanying drawings, Figure 5As shown, the first abutting end 4322 is in the shape of a circular arc, so that the first abutting end 4322 abuts against the button 3 through the circular arc surface thereof, so that the button 3 is more smooth when driving the driving member 4 to rotate.

[0097] As shown in the accompanying drawings, Figure 6 As shown, from the end of the first abutting end 4322 connected to the elastic arm segment 4321 to the free end thereof (the free end is the outermost end of the first abutting end 4322 and is used to abut against the button 3), the wall thickness of the first abutting end 4322 gradually increases, and the wall thickness of the elastic arm segment 4321 is less than or equal to the minimum wall thickness of the first abutting end 4322.

[0098] Wherein, the wall thickness mentioned above refers to the dimension of the elastic arm segment 4321 and the first abutting end 4322 in the direction perpendicular to the button 3.

[0099] Through the above arrangement of the wall thickness of the first abutting end 4322, the structural stability is stronger and is not easy to deform, which is beneficial to increase the driving reliability between the first abutting end 4322 and the button 3. Through the above arrangement of the wall thickness of the elastic arm segment 4321, the elastic deformation effect is improved.

[0100] For example, the first abutting end 4322 includes a circular arc abutting surface, and first and second side surfaces located on both sides of the circular arc abutting surface, the first ends of the first and second side surfaces are connected to the circular arc abutting surface, the second ends of the first and second side surfaces are connected to the elastic arm segment 4321, and the distance between the first and second side surfaces gradually decreases from the first ends thereof to the second ends thereof. For example, the first and second side surfaces can be inclined planes.

[0101] For example, from the end of the elastic arm segment 4321 connected to the first abutting end 4322 to the other end of the elastic arm segment 4321 connected to the driving body part 41, the wall thickness of the elastic arm segment 4321 can be the same.

[0102] In some examples, referring to Figure 5 and Figure 6 The rigid arm 431 includes a rigid arm segment 4311 and a second abutting end 4312, one end of the rigid arm segment 4311 is connected to the driving body part 41, and the other end of the rigid arm segment 4311 is connected to the second abutting end 4312.

[0103] Through the above definition of the structure of the rigid arm segment 4311, the rigid arm segment 4311 always maintains structural stability and position stability relative to the driving body part 41, and further, the length, thickness and width thereof can be adjusted to optimize the above effects. For example, the thickness and width of the rigid arm segment 4311 are greater than the thickness and width of the elastic arm segment 4321, for example, the ratio between them can be 2 to 5 times.

[0104] In some examples, reinforcing structures can also be arranged on the bottom and / or sides of the rigid arm segment 4311 to enhance the structural strength of the rigid arm segment 4311.

[0105] The structure of the second abutting end 4312 can be the same as or similar to that of the first abutting end 4322, for example, see Figure 5 and Figure 6 The second abutting end 4312 is also arranged in a circular arc shape, so that the rotation of the button 3 to drive the driving member 4 is smoother.

[0106] In the embodiments of the present application, the number of rigid arms 431 and elastic arms 432 can be one, two or more, and the number of rigid arms 431 and elastic arms 432 can be the same or different.

[0107] As a typical example, see Figure 5 and Figure 6 The number of rigid arms 431 is two, and the two rigid arms 431 are arranged in a spaced manner to form a containing space, and the elastic arm 432 is arranged in a suspended manner in the containing space. By arranging the elastic arm 432 between the two rigid arms 431, i.e., the two rigid arms 431 are symmetrically arranged on both sides of the elastic arm 432, the purpose of optimizing the above effect is achieved.

[0108] In some examples, as shown in Figure 3 and Figure 4 The button 3 includes a driving rib 31, and the driving rib 31 elastically abuts against the second driving part 43.

[0109] The driving rib 31 is arranged on the bottom of the button 3 at a position corresponding to the second driving part 43. When the driving rib 31 is arranged on the button 3, the above-mentioned abutment or driving of the second driving part 43 by the button 3 can be understood as the abutment or driving of the second driving part 43 by the driving rib 31 on the button 3.

[0110] The number and position of the driving rib 31 on the button 3 are determined according to the specific arrangement of the rigid arm 431 and the elastic arm 432. One corresponding driving rib 31 is configured for the first abutting end 4322 of each elastic arm 432, and one corresponding driving rib 31 is configured for the second abutting end 4312 of each rigid arm 431. For multiple driving ribs 31 located on the same side, any two adjacent driving ribs 31 can be connected or not connected, and in the connected case, the structural stability of the driving rib 31 can be improved.

[0111] For example, in the second driving part 43 of the driving member 4, the two rigid arms 431 are symmetrically arranged on both sides of the elastic arm 432, so see Figure 7Three driving ribs 31 are arranged on the button 3 to correspond to one first abutting end 4322 and two second abutting ends 4312 respectively.

[0112] Further, the middle driving rib 31 can be connected with the two driving ribs 31 on the two sides through connecting ribs.

[0113] As described above, the elastic structure can be arranged on the second driving part 43, and can also be arranged on the button 3. When the driving rib 31 is arranged on the button 3, the driving rib 31 can have the elastic structure.

[0114] In some examples, the second driving part 43 includes the rigid arm 431 and the elastic arm 432 arranged side by side, and then the driving rib 31 can be designed as a rigid rib, that is, the driving rib 31 is a rigid structure and does not change in structure during operation.

[0115] The driving rib 31 is used to drive the second driving part 43, which is beneficial to increase the reliability and sensitivity of the transmission of the acting force between the two.

[0116] In other examples, the elastic structure can be arranged on the driving rib 31, as shown in Figure 10 The driving rib 31 includes an elastic rib, and the second driving part 43 is a rigid driving part. For example, one end of the driving rib 31 is connected to the bottom of the button 3, and the other end of the driving rib 31 extends downward and is located below the button 3, so that the driving rib 31 is arranged in a suspended manner and can stretch and contract in the up-down direction perpendicular to the button 3.

[0117] In some examples, the driving rib 31 includes an elastic rib, which is used to abut the abutting end of the rigid second driving part 43; in other examples, the driving rib 31 includes an elastic rib and a rigid rib arranged side by side, which are used to abut different positions of the abutting end of the rigid second driving part 43 respectively.

[0118] As described above, by arranging the elastic structure on the driving rib 31 and the second driving part 43 being a rigid driving part, the same effect of reducing the dialing feeling of the button 3, effectively avoiding the abnormal sound of the switch shaking, and effectively avoiding the virtual position of the button 3 can be achieved.

[0119] In some examples, the abutting end of the second driving part 43 of the driving member 4 away from the driving body part 41, for example, can be the first abutting end 4322 and the second abutting end 4312 described above.

[0120] These abutting ends are arranged in an upwardly convex manner relative to the driving body part 41, which is beneficial to make the driving of the button 3 on the driving member 4 more efficient and reduce the swing angle of the button 3.

[0121] The first driving part 42 of the driving member 4 is hinged to the corresponding side of the first end of the transition member 5. One of the corresponding sides of the first driving part 42 and the transition member 5 is provided with a shaft, and the other is provided with a hole. The shaft and the hole are rotated together to achieve the hinge.

[0122] Appendix Figure 6 The example shows that the first driving part 42 of the driving member 4 is provided with a shaft hole 420. For example, the first driving part 42 includes two support blocks arranged opposite each other, the two support blocks cooperate to form an accommodating space, and each of the two support blocks has a shaft hole 420.

[0123] Accordingly, see Figure 6 Each of the corresponding positions on the rotating side of the first end of the transition piece 5 is connected to a connecting shaft 52. In application, the rotating side of the first end of the transition piece 5 is located in the accommodating space between the two support blocks, and the connecting shaft 52 on it is located inside the shaft hole 420 on the corresponding support block. In this way, the hinge connection between the transition piece 5 and the driving piece 4 can be realized.

[0124] The drive body 41 of the drive member 4 is hinged to the pressure member 2. In some examples, such as the attached... Figure 6 As shown, a drive shaft 411 is provided at the bottom of the drive body 41. The drive shaft 411 is hinged to the corresponding position on the pressure member 2. For example, the drive shaft 411 is located at the middle position of the bottom of the drive body 41, and both ends of the drive shaft 411 protrude from both sides of the drive body 41. The distribution direction of the two sides of the drive body 41 involved here is perpendicular to the distribution direction of the two pressing sides of the button 3.

[0125] For the drive component 4, the drive component shaft 411 is located at the bottom, and the abutting end of the second drive part 43 is located at the top of one side of the drive component 4, so that the drive component 4 acts as a lever to smoothly transmit the pressing force of the button 3 to the transition component 5.

[0126] As attached Figure 6 As shown, two first hinge holes 221 are provided at the corresponding positions on the top of the pressure member 8. Each first hinge hole 221 is provided by a first bracket 222. The two first brackets 222 are hinged to the two ends of the drive shaft 411 one by one.

[0127] By providing a first hinge hole 221 on the first bracket 222, the end of the drive shaft 411 is fitted into the corresponding first hinge hole 221, thereby achieving the hinge between the drive member 4 and the pressure member 2.

[0128] For example, the drive shaft 411 can be cylindrical or an irregular shape with a certain degree of rotational freedom, such as a smoothly transitioned triangle. In some examples, the drive shaft 411 can be designed to allow the drive 4 to rotate clockwise and counterclockwise by a specific angle only. The first hinge hole 221 can be designed to fit the shape of the drive shaft 411.

[0129] Understandably, the aforementioned first bracket 222 can be arranged individually on the top surface of the pressure member 2, and for some first brackets 222 located on the side, they can also be provided by the side frame of the pressure member 2.

[0130] Furthermore, as shown in the appendix Figure 8 As shown, the pressure member 2 is provided with a support rib 21, which further connects to the support rib 21. Figure 3 The support rib 21 abuts against the bottom wall of the drive shaft 411. The bottom of the part of the drive shaft 411 located between its two ends overlaps the support rib 21, which makes the rotation process of the drive 4 more stable and reliable, and helps to maintain the structural stability of the drive 4 and the pressure member 2.

[0131] The hinge between transition piece 5 and pressure piece 2 can be achieved in the following way: (combination) Figure 6 It can be seen that the transition member 5 has a T-shaped structure, which includes a horizontal section 501 and a vertical section 502 connected to the bottom middle position of the horizontal section 501. A transition member pivot 51 is arranged at the middle position of each side of the horizontal section 501, and a connecting shaft 52 is arranged at each end of the horizontal section 501.

[0132] Combination Figure 8 It is known that the first end (i.e. the top end) of the pressure member 2 has two opposingly arranged second supports 232 in the middle, and each second support 232 has a second hinge hole 231. A through hole 132 is provided on the top surface of the pressure member 2 located between the two second supports 232 for passing through the vertical section 502 of the transition member 5.

[0133] For example, the transition member shaft 51 can be cylindrical or an irregular shape with a certain degree of rotational freedom, such as a smoothly transitioning triangle. In some examples, the transition member shaft 51 can be designed to allow the transition member 5 to rotate clockwise and counterclockwise by a specific angle only. The second hinge hole 231 can be designed to match the shape of the drive member shaft 411.

[0134] The base assembly 1 can be designed according to the type of switch, and the button 3 is hinged to the uppermost one in the base assembly 1 so that the button 3 can be pressed and rotated as the switch panel. For example, the base assembly 1 includes a base 11, a support frame 12, and an optional fixing frame 13.

[0135] In some examples, as shown in the accompanying drawings Figure 2 - the accompanying drawings Figure 3 The seat body assembly 1 includes a base 11, a support frame 12 and a fixing frame 13. The base 11 has a receiving cavity for accommodating the pressing piece 2 and the switch function assembly 6. The support frame 12 is arranged on the outer side of the upper part of the base 11. The fixing frame 13 is connected to the support frame 12 and covers the receiving cavity. Further combining Figure 9 , the fixing frame 13 has a first hinge part 131 for hinging with the button 3 and a through hole 132 for exposing the second driving part 43.

[0136] The fixing frame 13 is fixedly connected to the support frame 12 and covers the driving piece 4, the transition piece 5 and other components. The first hinge part 131 is arranged on the fixing frame 13 for hinging with the button 3, so that the button 3 can be pressed and rotated.

[0137] The through hole 132 is arranged on the fixing frame 13 to expose the second driving part 43 of the driving piece 4, so that the driving rib 31 on the button 3 can penetrate the through hole 132 to abut against the second driving part 43. The bottom of the button 3 is provided with a second hinge part 32. One of the first hinge part 131 and the second hinge part 32 is arranged as a hole, and the other is arranged as a shaft. The shaft can be limited in the hole and can only rotate and cannot move in other directions.

[0138] For example, Figure 9 The first hinge part 131 on the fixing frame 13 is in the shape of a shaft, and the second hinge part 32 on the button 3 is formed on the support plate and is in the shape of a limiting hole. By applying an external force to press the button 3, the second hinge part 32 on the button 3 is clamped into the first hinge part 131 on the fixing frame 13, so that the button 3 can only be pressed and rotated and cannot be separated from the fixing frame 13 at will.

[0139] The structure of the switch function assembly 6 in the switch and its working principle will be briefly described below:

[0140] As shown in the accompanying drawings Figure 3 The switch function assembly 6 includes a pin assembly 61, a cantilever plate 62, a support piece 63, an outgoing terminal assembly 64 and an incoming terminal assembly (not shown in the drawings).

[0141] The outgoing terminal assembly 64 and the incoming terminal assembly are both fixed in the interior of the base 11. The incoming terminal assembly is electrically connected to the support piece 63, and the support piece 63 is movably connected to the bottom of the cantilever plate 62 to allow the cantilever plate 62 to swing. The outgoing terminal assembly 64 includes a static contact point for contacting a dynamic contact point on the cantilever plate 62. The vertical section 502 of the transition piece 5 is connected to the pin assembly 61, and the pin assembly 61 abuts against the top of the cantilever plate 62 to drive the cantilever plate 62 to swing.

[0142] In application, the user rotates the button 3, the rotating button 3 drives the transition piece 5 to rotate through the driving piece 4, the transition piece 5 transmits the driving force to the pin assembly 61, the pin assembly 61 slides on the flap 62, and the flap 62 swings, the swinging flap 62 drives the moving contact to contact or separate from the corresponding static contact, and the purpose of on-off current is achieved.

[0143] In conclusion, the switch provided by the embodiment of the present application has at least the following advantages:

[0144] (1) The driving piece 4 is arranged in linkage with the button 3 and the transition piece 5, the rotation of the button 3 is amplified and transmitted to the transition piece 5, the small swing angle design of the button 3 is realized, and the switch can be designed as an ultra-thin switch.
