[0002] A switch is a device used to control the on / off state of a lighting fixture or other electrical circuit. The silver bridge assembly of the switch can swing in response to the movement of the switch button. The silver bridge assembly includes silver alloy contacts. When the switch is pressed, the silver bridge assembly moves accordingly, causing its contacts to make contact with or separate from fixed terminals inside the switch. Utility Model Content

[0003] In one aspect of this disclosure, a switch is provided, the switch including a housing, a first terminal block, a second terminal block, a oscillating assembly, and a contact conductive assembly. The first terminal block is disposed within the housing and includes a first stationary contact. The second terminal block is disposed within the housing and includes a second stationary contact, the second stationary contact and the first stationary contact being located at one end of the housing in a first direction and adjacent to each other in a second direction, the first direction being perpendicular to the second direction.

[0019] As described above, the silver bridge assembly of a switch can swing in response to the action of the switch button. When the switch is pressed, the silver bridge assembly moves accordingly, causing its contacts to make or separate from the fixed terminals inside the switch. However, due to layout considerations, the terminals of conventional switches are spaced far apart, resulting in a large size for the silver bridge assembly, which cannot meet the requirements for miniaturization design. Embodiments of this disclosure provide a switch to at least partially solve the above-mentioned problems. In the following, [further details will be provided in conjunction with...] Figures 1 to 16 The principles of this disclosure are described.

[0020] Figure 1 A schematic diagram of the structure of a switch 100 according to some embodiments of the present disclosure is shown. Figure 2 A cross-sectional view of a switch 100 according to some embodiments of the present disclosure is shown. Figure 3 A schematic diagram of the structure of a first terminal 2, a second terminal 3, a third terminal 4, and a pair of magnetic elements 7 according to some embodiments of the present disclosure is shown. Figure 4 A schematic diagram of the structure of the oscillating assembly 5 and the contact conductive assembly 6 according to some embodiments of the present disclosure is shown. Figure 5 A schematic diagram of the structure of a contact conductive assembly 6 according to some embodiments of the present disclosure is shown. For example... Figures 1 to 5 As shown, the switch 100 described herein includes a housing 1, a first terminal block 2, a second terminal block 3, a third terminal block 4, a oscillating assembly 5, and a contact conductive assembly 6.

[0021] refer to Figure 2 and Figure 3 In some embodiments, the first terminal 2 is disposed within the housing 1 and includes a first stationary contact 21. The second terminal 3 is disposed within the housing 1 and includes a second stationary contact 31. The second stationary contact 31 and the first stationary contact 21 are located at one end of the housing 1 in a first direction X and are adjacent to each other in a second direction Y. The first direction X is perpendicular to the second direction Y.

[0022] refer to Figure 2 and Figure 4In some embodiments, the oscillating assembly 5 is movably disposed within the housing 1. The contact conductive assembly 6 is rotatably disposed within the housing 1. The contact conductive assembly 6 is movably connected to the oscillating assembly 5 so as to be driven by the oscillating assembly 5 when the oscillating assembly 5 moves.

[0023] refer to Figure 3 and Figure 5 In some embodiments, the contact conductive assembly 6 includes a mounting base 61 and a conductive element 62. The conductive element 62 is located at one end of the mounting base 61 in a first direction X and is adapted to abut against the second stationary contact 31 and the first stationary contact 21.

[0024] According to embodiments of this disclosure, the conductive element 62 is adapted to abut against the second stationary contact 31 and the first stationary contact 21. With the second stationary contact 31 and the first stationary contact 21 adjacent to each other in the second direction Y, the dimension of the conductive element 62 along the second direction Y is significantly reduced, and the dimension of the mounting base 61 along the second direction Y is simultaneously reduced, thereby reducing the size of the contact conductive assembly 6 to meet the requirements of miniaturization. Furthermore, the contact conductive assembly 6 is movably connected to the swing assembly 5, and when the swing assembly 5 moves, the contact conductive assembly 6 can move with the swing assembly 5 to abut or separate from the stationary contact.

[0025] In some embodiments, switch 100 may include a single-pole switch. The contact conductive assembly 6 includes a mounting base 61 and a single conductive element 62. The conductive element 62 is located at one end of the mounting base 61 in a first direction X and is adapted to abut against the second stationary contact 31 and the first stationary contact 21.

[0026] Continue to refer to Figures 3 to 5 In other embodiments, switch 100 may further include a two-way switch. The two-way switch may further include a third terminal block 4. The third terminal block 4 is disposed within housing 1 and includes a third stationary contact 41. The second terminal block 3 also includes a fourth stationary contact 32. The fourth stationary contact 32 and the third stationary contact 41 are located at the other end of housing 1 in a first direction X and are adjacent to each other in a second direction Y. The contact conductive assembly 6 includes a pair of conductive elements 62. One of the conductive elements 62 is located at one end of mounting base 61 in the first direction X and is adapted to abut against the second stationary contact 31 and the first stationary contact 21. The other conductive element 62 is located at the other end of mounting base 61 in the first direction X and is adapted to abut against the fourth stationary contact 32 and the third stationary contact 41.

[0027] In the following text, the exemplary structure and principle of this disclosure will be mainly illustrated using switch 100, including a two-way switch. Switch 100 including a single-way switch is the same or similar, and will not be described in detail here.

[0028] It should be noted that the reference Figure 2The oscillating component 5 is adapted to drive the contact conductive component 6 to switch between a first conductive position and a second conductive position. (Continue to refer to...) Figure 3 and Figure 5 When the contact conductive assembly 6 is in the first conductive position, one of the paired conductive members 62 abuts against the second stationary contact 31 and the first stationary contact 21, while the other conductive member 62 is separated from the fourth stationary contact 32 and the third stationary contact 41. When the contact conductive assembly 6 is in the second conductive position, one of the paired conductive members 62 is separated from the second stationary contact 31 and the first stationary contact 21, while the other conductive member 62 abuts against the fourth stationary contact 32 and the third stationary contact 41.

[0029] According to embodiments of this disclosure, one of the paired conductive elements 62 is adapted to abut against the second stationary contact 31 and the first stationary contact 21, and the other conductive element 62 is adapted to abut against the fourth stationary contact 32 and the third stationary contact 41. When the second stationary contact 31 and the first stationary contact 21 are adjacent to each other in the second direction Y, and the fourth stationary contact 32 and the third stationary contact 41 are adjacent to each other in the second direction Y, the size of the paired conductive elements 62 along the second direction Y is significantly reduced, and the size of the mounting base 61 along the second direction Y is simultaneously reduced, thereby reducing the size of the contact conductive assembly 6 to meet the requirements of miniaturization.

[0030] Continue to refer to Figure 3 In some embodiments, the switch 100 may further include at least one magnetic element 7 disposed within the housing 1. When the switch 100 includes a two-way switch, the at least one magnetic element 7 may include a pair of magnetic elements 7. One of the pair of magnetic elements 7 is located between the second stationary contact 31 and the first stationary contact 21. The other magnetic element 7 of the pair of magnetic elements 7 is located between the fourth stationary contact 32 and the third stationary contact 41. In this way, when an electric arc is generated between the conductive element 62 and the corresponding stationary contact, the magnetic element 7 generates a magnetic field and subjectes the electric arc to a Lorentz force. Under the action of the Lorentz force, the electric arc is elongated, thereby achieving a rapid arc extinguishing effect. The arc extinguishing principle of the switch 100 will be discussed in detail below. Figure 10 Provide a detailed description.

[0031] In addition, continue to refer to Figure 3 and Figure 5 By placing the magnetic element 7 between adjacent pairs of stationary contacts in the second direction Y, the pairs of stationary contacts can be close to each other in the second direction Y, which helps to reduce the size of the pairs of conductive elements 62 in the second direction Y, thereby reducing the size of the contact conductive assembly 6.

[0032] Continue to refer to Figure 3In some embodiments, each magnetic element 7 may have a first side 71 and a second side 72 disposed along the second direction Y. The magnetic poles of the first side 71 may be opposite to those of the second side 72. The polarity of the magnetic element 7 is not required. For example, if one side of the first side 71 and the second side 72 of each magnetic element 7 is an N pole, then correspondingly, the other side of the first side 71 and the second side 72 is an S pole. Furthermore, the magnetic poles of the first sides 71 of a pair of magnetic elements 7 may be the same or opposite. The magnetic poles of the second sides 72 of a pair of magnetic elements 7 may also be the same or opposite. In this way, it is advantageous to reduce the assembly cost of the magnetic elements 7.

[0033] Figure 6 and Figure 7 It shows Figure 5 A partial structural schematic diagram of the contact conductive component 6 is shown. Figures 5 to 7 As shown, in some embodiments, the mounting base 61 may include a mating portion 611 and a pair of mounting portions 612. The mating portion 611 is disposed between the pair of mounting portions 612 in a first direction X. Pairs of conductive members 62 are each connected to a corresponding mounting portion 612 in the pair of mounting portions 612. The mating portion 611 is movably connected to and driven by the swing assembly 5. The operating principle of the mating portion 611 being driven by the swing assembly 5 will be explained below. Figure 9 Provide a detailed description.

[0034] refer to Figure 6 In some embodiments, each mounting portion 612 includes a first pair of side plates 6121, a second pair of side plates 6122, and a support portion 6123. The first pair of side plates 6121 are disposed along a first direction X. The second pair of side plates 6122 are disposed along a second direction Y. The support portion 6123 is disposed between the first pair of side plates 6121 and spaced apart from the second pair of side plates 6122. A conductor 62 passes through the mounting portion 612. The conductor 62 is disposed on the support portion 6123 and supported by the support portion 6123, allowing the conductor 62 to swing relative to the support portion 6123. It is understood that due to contact erosion or assembly reasons, the heights of the paired stationary contacts in the second direction Y may be unequal. By allowing the conductor 62 to swing relative to the support portion 6123, the connection relationship between the conductor 62 and the paired stationary contacts can be balanced, thereby avoiding the problem of uneven contact between the conductor 62 and the paired stationary contacts.

[0035] Due to the miniaturization design and manufacturing limitations of the contact conductive component 6, it is difficult to provide a rotating shaft or hole on the conductive element 62 at low cost to make the conductive element 62 swing. Therefore, [further details are needed]. Figure 5 and Figure 6In some embodiments, the conductive member 62 may include a middle portion 621 and a pair of conductive portions 622. The middle portion 621 is disposed on the support portion 6123, and the conductive member 62 swings relative to the support portion 6123 via the middle portion 621. In this way, it is not necessary to provide a rotating shaft or hole on the conductive member 62 to allow the conductive member 62 to swing, which is beneficial for the miniaturization design of the contact conductive assembly 6 and simplifies the manufacturing process. The pair of conductive portions 622 are arranged at intervals from each other along the second direction Y. Each conductive portion 622 has a first end 6221 and a second end 6222. The first end 6221 is connected to the middle portion 621, and the second end 6222 extends out of the mounting portion 612 and is adapted to abut against one of the first stationary contact 21, the second stationary contact 31, the third stationary contact 41, and the fourth stationary contact 42.

[0036] To ensure that the middle part 621 can swing smoothly around the support part 6123, continue to refer to... Figure 2 , Figure 5 and Figure 6 In some embodiments, the switch 100 further includes a press panel 8. The press panel 8 is pressably connected to and covers the housing 1. The middle portion 621 is bendable and can arch toward the press panel 8. The side of the support portion 6123 adjacent to the press panel 8 can arch toward the middle portion 621, and the arched position can abut against the bend position of the middle portion 621.

[0037] Figure 8 A schematic diagram of the structure of the magnetically attracted member 613 and the magnetic member 7 according to some embodiments of the present disclosure is shown. Figures 6 to 8 As shown, in some embodiments, the mounting base 61 further includes a pair of magnetically attracted members 613. Each pair of magnetically attracted members 613 is disposed on the mounting portion 612, for example, on the side of the corresponding support portion 6123 facing away from the pressing panel 8. Each pair of magnetically attracted members 613 is magnetically attracted by a corresponding magnetic element 7. The magnetic element 7 may include, for example, a permanent magnet. On one hand, when the conductive portion 622 of the conductive member 62 abuts against the corresponding contact, the magnetically attracted member 613 located on the same side of the conductive member 62 is adjacent to the corresponding magnetic element 7 and is suitable for being magnetically attracted by the magnetic element 7. This magnetic attraction force firmly abuts the mounting portion 612 and the conductive member 62 against the corresponding contact, thereby helping to reduce the contact resistance between the conductive portion 622 and the contact. On the other hand, during the process of the conductive portion 622 disconnecting from the corresponding contact, the magnetically attracted member 613 moves away from the magnetic element 7. Due to the magnetic attraction properties, when the distance between the magnetically attracted part 613 and the magnetic part 7 is slightly increased, the magnetic attraction force of the magnetic part 7 on the magnetically attracted part 613 decreases sharply, thereby causing the conductive part 622 to quickly disconnect from the corresponding contact, which helps to reduce the arcing time. In addition, it also helps to reduce the jumping amplitude of the conductive part 622 during the disconnection process, thereby reducing the risk of contact welding.

[0038] Continue to refer to Figure 7 and Figure 8 In some embodiments, the magnetically attracted member 613 may include a main body 6131 and a pair of extensions 6132. The pair of extensions 6132 are disposed on the main body 6131 and each extends in a direction away from the pressing panel 8. (Continuing to refer to...) Figure 8 When the conductive portion 622 of the conductive member 62 abuts against the corresponding contact, the paired extensions 6132 of the magnetically attracted member 613 located on the same side of the conductive member 62 partially overlap with the magnetic member 7 in the second direction Y, so as to be magnetically attracted by the magnetic member 7. Furthermore, since the paired extensions 6132 partially overlap with the magnetic member 7 in the second direction Y, the magnetic attraction force of the magnetic member 7 on the magnetically attracted member 613 decreases sharply when the distance between the magnetically attracted member 613 and the magnetic member 7 is increased slightly.

[0039] According to embodiments of this disclosure, the magnetically attracted member 613 can be connected to the magnetically attracted member 613 in any manner. For example, refer to... Figure 7 In some embodiments, the main body 6131 includes a first hole 6133 and a second hole 6134. The first hole 6133 is located at one end of the main body 6131 in a first direction X, and the second hole 6134 is located at the other end of the main body 6131 in the first direction X. Correspondingly, a snap-fit ​​portion 6124 is provided on the side plate of the opposite-fitting portion 611 in the first pair of side plates 6121. A connecting portion 6125 is provided on the side of the support portion 6123 opposite to the pressing panel 8. The first hole 6133 can engage with the snap-fit ​​portion 6124, and the second hole 6134 can engage with the connecting portion 6125.

[0040] Return to reference Figure 5 and Figure 6 In some embodiments, the contact conductive assembly 6 further includes a pair of retaining covers 63. Each pair of retaining covers 63 is pushed into a corresponding mounting portion 612 in a direction toward the mating portion 611. Each pair of retaining covers 63 covers and presses against a corresponding conductive element 62, so that the conductive element 62 is pivotally mounted on the support portion 6123. The pushing direction can be perpendicular to the second direction Y. In this way, the assembly direction of the retaining cover 63 is perpendicular to the direction of force it experiences during operation, which reduces the assembly force and allows the retaining cover 63 to withstand greater impact forces, thereby preventing the retaining cover 63 from being damaged by impact.

[0041] Continue to refer to Figure 6In some embodiments, a snap fastener 631 is provided on one side of the fixing cover 63 adjacent to the mating portion 611. The mating portion 611 may include a pair of protrusions 6111. The snap fasteners 631 of the pair of fixing covers 63 are each connected to and limited by the corresponding protrusion 6111 in the pair of protrusions 6111, so that the fixing cover 63 is securely assembled to the mounting base 61. In addition, since the snap fastener 631 is provided on one side of the fixing cover 63 adjacent to the mating portion 611, it is also beneficial to reduce the impact force on the snap fastener 631, thereby avoiding damage to the snap fastener 631 and affecting the assembly of the fixing cover 63.

[0042] Return to reference Figure 2 In some embodiments, the housing 1 includes a base 11, a cover 12, and a surrounding member 13. A first terminal 2, a second terminal 3, a third terminal 4, and a contact conductive assembly 6 are all disposed within the internal cavity of the base 11. A pair of magnetic members 7 can be pushed into the base 11 in a direction toward the pressing panel 8. The cover 12 can cover the opening of the base 11.

[0043] refer to Figure 2 , Figure 4 and Figure 5 The oscillating assembly 5 can pass through the cover plate 12 and is partially disposed within the mating portion 611. The oscillating assembly 5 is movably connected to the mating portion 611 to drive the contact conductive assembly 6 to oscillate via the mating portion 611. The surrounding member 13 can be disposed around the base 11. A pair of rotating members 91 are rotatably connected to the cover plate 12, and the opposite ends of the pair of rotating members 91 are pressed by the pressing panel 8 to rotate relative to the cover plate 12 under the drive of the pressing panel 8. The oscillating assembly 5 covers the adjacent ends of the pair of rotating members 91 to oscillate driven by the pair of rotating members 91. The oscillating assembly 5 can be connected to the mating portion 611 via a pair of elastic members 92. The pressing panel 8 covers the surrounding member 13, the oscillating assembly 5, and the pair of rotating members 91 and is oscillatingly connected to the base 11.

[0044] Figure 9 A schematic diagram of the engagement of the swing assembly 5 and the mating part 611 according to some embodiments of the present disclosure is shown. The following will be combined with... Figure 2 and Figure 9 To illustrate the schematic working process of switch 100.

[0045] refer to Figure 2 The pressing panel 8 is pressed, pressing one end of the rotating member 91. The other end of the rotating member 91 is lifted, driving the swing assembly 5 to swing. (Reference) Figure 9During the oscillation process, the elastic element 92 can be compressed and store energy, and the oscillation assembly 5 can drive the contact conductive assembly 6 to oscillate by pressing the inner wall of the mating part 611. Then, after the oscillation assembly 5 oscillates to the middle position, the elastic element 92 begins to release energy and drive the oscillation assembly 5 to oscillate. During the oscillation process, the oscillation assembly 5 is adapted to drive the contact conductive assembly 6 to oscillate, so that the contact conductive assembly 6 switches between a first conductive position and a second conductive position.

[0046] Figure 10 A schematic diagram of arc extinguishing of a switch 100 according to some embodiments of the present disclosure is shown. For example... Figure 10 As shown, when current flows from the conducting element 62 to the corresponding stationary contact, an electric arc is generated between the second end 6222 of the conducting element 62 and the stationary contact during the breaking process. The magnetic field direction Y between the second end 6222 and the stationary contact of the magnetic element 7 is as follows. Figure 10 As shown. According to the left-hand rule, the direction of the Lorentz force F on the electric arc is as follows. Figure 10 As shown. Under the action of the Lorentz force, the electric arc is elongated to achieve a rapid arc extinguishing effect. When either the direction of current flow or the direction Y of the magnetic field between the second end 6222 and the stationary contact of the magnetic component 7 changes, the direction of the Lorentz force on the arc changes accordingly. Figure 10 The Lorentz force F shown is in the opposite direction, so as to achieve the same effect of rapid arc extinguishing. In this way, the switch 100 according to the embodiment of this disclosure meets the requirement of non-polar arc extinguishing.

[0047] Continue to refer to Figure 10 In some embodiments, each conductive portion 622 may include a pair of third sides 6223. The pair of third sides 6223 are arranged along a first direction X and are each inclined relative to the first direction X. The distance between the pair of third sides 6223 gradually decreases along the direction away from the intermediate portion 621. That is, the end of the conductive portion 622 away from the intermediate portion 621 gradually narrows. In this way, the conductive portion 622 has sufficient space in the first direction X for the arc to be elongated.

[0048] Figure 11 A schematic diagram of the structure of a first terminal 2, a second terminal 3, a third terminal 4, a contact conductive assembly 6, and a pair of magnetic elements 7 according to other embodiments of the present disclosure is shown. Figure 12 and Figure 13 It shows Figure 11 A partial structural schematic diagram of the contact conductive component 6 is shown. Figures 11 to 13 The contact conductive component 6 shown is... Figures 5 to 7The contact conductive assembly 6 shown has a similar structure, with the main differences being the structure of the mounting part 612, the conductive element 62, the magnetically attracted element 613, and the pin 64. The following text will primarily describe the differences between the two, while the identical parts will not be repeated.

[0049] like Figures 11 to 13 As shown, in some embodiments, the conductive member 62 may further include a central portion 621, a pair of conductive portions 622, and a pair of protrusions 623. The central portion 621 may be arranged in a straight line. The pair of conductive portions 622 are spaced apart from each other on the central portion 621 in a second direction Y. The pair of protrusions 623 are spaced apart from each other on the central portion 621 in a first direction X. The ends of the conductive portions 622 opposite to the central portion 621 and the ends of the protrusions 623 opposite to the central portion 621 are located on opposite sides of the central portion 621.

[0050] refer to Figure 13 Furthermore, the magnetically attracted member 613 may include a main body 6131 and a pair of extensions 6132. The pair of extensions 6132 are disposed on the main body 6131 and each extends in a direction away from the pressing panel 8. The pair of extensions 6132 can partially overlap with the magnetic member 7 in the second direction Y to reduce arcing time and lower the risk of contact welding. The main body 6131 may include a pair of first holes 6133. The pair of first holes 6133 are arranged along the second direction Y. (Continue referring to...) Figure 12 and Figure 13 Correspondingly, the mounting part 612 may include a pair of snap-fit ​​parts 6124. The magnetically attracted part 613 can be pushed into the mounting part 612 along the direction of the contact conductive assembly 6 pointing to the pressing panel 8, and snap-fit ​​with the pair of snap-fit ​​parts 6124 through the pair of first holes 6133 to improve the firmness of the assembly.

[0051] Continue to refer to Figures 11 to 13 In some embodiments, the mounting portion 612 may further include a pair of first through holes 6126. The pair of first through holes 6126 may be arranged along a first direction X. After the magnetic member 613 is pushed into the mounting portion 612, the conductive member 62 may also be pushed into the mounting portion 612 in the direction of the contact conductive assembly 6 pointing towards the pressing panel 8, such that the pair of protrusions 623 are located within the pair of first through holes 6126. The contact conductive assembly 6 may further include a pair of pins 64. Each pair of pins 64 passes through the pair of protrusions 623 of the corresponding conductive member 62 and is connected to the corresponding mounting portion 612. In this way, the conductive member 62 may swing around the corresponding pin 64 to balance the connection relationship between the conductive member 62 and the pair of stationary contacts, thereby avoiding the problem of uneven contact between the conductive member 62 and the pair of stationary contacts. In addition, since the conductive member 62 swings around the corresponding pin 64, it is beneficial to improve the reliability of the swing of the conductive member 62.

[0052] refer to Figure 11 and Figure 12 Furthermore, the mounting portion 612 may also include a second through hole 6127, which may be disposed between a pair of first through holes 6126. A snap-fit ​​element (not shown in the figure) may be disposed within the second through hole 6127. The snap-fit ​​element may be pressed into the mounting portion 612 along the direction of the pressing panel 8 toward the contact conductive assembly 6 and snapped onto the pin 64 to limit the pin 64, thereby preventing the pin 64 from falling out of the mounting portion 612.

[0053] Continue to refer to Figure 13 Furthermore, in order to avoid interference between the conductive member 62 and the magnetically attracted member 613, a pair of openings can be provided on the middle part 621 of the conductive member 62, and the pair of extensions 6132 can pass through the pair of openings.

[0054] Figure 14 A schematic diagram of the structure of a first terminal 2, a second terminal 3, a third terminal 4, a contact conductive assembly 6, and a pair of magnetic elements 7 according to other embodiments of the present disclosure is shown. Figure 15 A schematic diagram of the structure of the oscillating assembly 5 and the contact conductive assembly 6 according to other embodiments of the present disclosure is shown. Figure 16 It shows Figure 15 The exploded view of the swing assembly 5 and the contact conductive assembly 6 is shown. Figures 14 to 16 The swing assembly 5 and the contact conductive assembly 6 shown are... Figures 5 to 7 The swing assembly 5 and the contact conductive assembly 6 shown have similar structures, with the main differences being the structures of the mating part 611, the mounting part 612, the conductive part 62, and the pin 64, and the absence of the magnetically attracted part 613. The following text will primarily describe the differences between the two, while the identical parts will not be repeated.

[0055] like Figures 14 to 16 As shown, in some embodiments, the conductive member 62 may further include a middle portion 621, a pair of conductive portions 622, and a pair of protrusions 623. The middle portion 621 may be arranged horizontally. The pair of conductive portions 622 are spaced apart from each other on the middle portion 621 in the second direction Y. The pair of protrusions 623 are spaced apart from each other on the middle portion 621 in the height direction Z of the switch 100. The ends of the conductive portions 622 opposite to the middle portion 621 and the ends of the protrusions 623 opposite to the middle portion 621 are located on opposite sides of the middle portion 621. The height direction Z may be perpendicular to the first direction X and the second direction Y.

[0056] Continue to refer to Figures 14 to 16In some embodiments, since the paired protrusions 623 are spaced apart and form a space, the paired protrusions 623 can abut against the outer surface of the mounting portion 612 to clamp the mounting portion 612. The contact conductive assembly 6 may also include a pair of pins 64. Each pair of pins 64 passes through the paired protrusions 623 of the corresponding conductor 62 and is connected to the corresponding mounting portion 612. In this way, the conductor 62 can swing about the corresponding pin 64 to balance the connection relationship between the conductor 62 and the paired stationary contacts, thereby avoiding the problem of uneven contact between the conductor 62 and the paired stationary contacts. In addition, since the conductor 62 swings about the corresponding pin 64, it is beneficial to improve the reliability of the swing of the conductor 62.

[0057] Continue to refer to Figure 15 Furthermore, the mounting portion 612 may also include a snap-fit ​​member 6128. The snap-fit ​​member 6128 engages with one end of the corresponding pin 64 to limit the pin 64, thereby preventing the pin 64 from falling out of the mounting portion 612. (Continue referring to...) Figure 15 and Figure 16 In some embodiments, the oscillating assembly 5 may include a pair of mating grooves 51. The pair of mating grooves 51 are disposed at one end of the oscillating assembly 5 opposite to the pressing panel 8. A mating portion 611 is movably disposed within the pair of mating grooves 51 so that the contact conductive assembly 6 is driven by the oscillating assembly 5. Furthermore, the oscillating assembly 5 may also be connected to the mating portion 611 via a pair of elastic members 92.
