Description

Technical Field

[0001] This invention relates to the field of DIP switch technology, specifically a DIP switch assembly. Background Technology

[0002] In existing DIP switch assemblies, a combination of DIP switches and printed circuit boards (PCBs) is typically used to switch circuit loops. While this traditional design is widely used in many applications, it also has some significant drawbacks and limitations. Routing on the PCB requires consideration of various factors such as signal integrity and electromagnetic compatibility, making the design and manufacturing process relatively complex. The manufacturing cost of PCBs is high, especially for high-density, multi-layer designs, increasing the overall product cost. Traditional DIP switch assemblies have relatively fixed functions, making it difficult to flexibly adjust or expand them to meet different needs. If either the DIP switch or the PCB fails, the entire assembly usually needs to be replaced, resulting in high maintenance costs.

[0003] Chinese Patent Publication No. CN116658866A, Publication Date: August 29, 2023, discloses a Chinese patent entitled "A Control Device Applicable to Multiple DIP Switches," comprising: a DIP switch box; a DIP switch board disposed inside the DIP switch box; a slider slidably connected to the DIP switch box and connected to the DIP switch board; and wires disposed on both sides of the DIP switch box and electrically connected to the DIP switch board. The DIP switch box includes: a bottom shell disposed outside the DIP switch board and connected to the wires; and a top cover disposed outside the DIP switch board and opposite to the bottom shell. The DIP switch board is a PCB board, which has high manufacturing costs, is difficult to adjust, and has high maintenance costs. Summary of the Invention

[0004] This invention provides a DIP switch assembly that achieves multi-level adjustment without using a printed circuit board by setting a connecting piece and a DIP switch, which facilitates maintenance and replacement and reduces costs.

[0005] A further objective of this invention is to simplify the structure and enable multi-level adjustment by providing a first connecting pin and a second connecting pin, thereby reducing manufacturing costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a DIP switch assembly, comprising a connecting piece and a plurality of connecting terminals, respectively fixed to a first connecting line and a second connecting line, the plurality of connecting terminals being respectively snapped into a plurality of connecting positions of the DIP switch; the connecting piece is provided with a first connecting foot and a second connecting foot that abut against each other at their tails, the first connecting foot and the second connecting foot being bent outwards and located at the top and bottom ends of the connecting piece respectively, the first connecting foot being provided with a stop hole; the plurality of connecting positions are respectively located at the upper and lower ends of opposite sides of the DIP switch connecting plate.

[0007] Preferably, the connecting piece is riveted to the first negative wire of the first connecting line, and several connecting terminals are respectively riveted to several second negative wires of the second connecting line. The second negative wire includes negative circuit one and negative circuit two 2.3. The riveting connection method improves the stability and reliability of the connection and reduces poor contact caused by vibration or impact. Riveting the connecting terminals directly to the sheath wire simplifies the assembly process and improves production efficiency.

[0008] Preferably, both the first and second connecting wires are equipped with wire clips, and the second connecting wire is a multi-core sheathed wire. The wire clip consists of two plates connected at the top, which clip into the wire clip slots on the upper cover. The two slots are located at the top of opposite sides of the upper cover, and the top of the slots is open. The second connecting wire is preferably a three-core sheathed wire, and the first connecting wire is preferably a two-core sheathed wire. The multi-core sheathed wire design increases the flexibility of the wiring and can adapt to different electrical connection requirements. The wire clip design ensures the stable fixation of the sheathed wire in the upper cover, reducing wire loosening caused by external forces.

[0009] Preferably, the connecting terminal is a cylindrical shell with flanges on its sidewalls and openings at both ends. A retaining ring is provided at the end of the connecting position near the second connecting line. The connecting terminal is preferably a copper terminal. The flanges are located at the edge of the hole in the connecting terminal and are angled outwards. The connecting position is an arc-shaped plate that conforms to the shape of the connecting terminal. The diameter of the retaining ring's hole is larger than the diameter of the connecting terminal. The connecting terminal is assembled on the connecting position, and the flanges are secured to the retaining ring. The flange design and the cooperation of the retaining ring ensure the stable fixation of the connecting terminal on the connecting position, reducing loosening. It also enhances conductivity; copper terminals have excellent conductivity, improving the circuit's transmission efficiency.

[0010] Preferably, both the first and second connecting feet are equipped with snap-fit ​​plates, which are inclined outwards. The first connecting foot is longer than the second connecting foot. The first connecting foot is located in the upper half of the connecting piece, and the second connecting foot is located in the lower half of the connecting piece. A mounting hole is provided at the abutment of their tails for installation inside the top cover. The snap-fit ​​plate design ensures stable fixation of the connecting feet within the top cover, reducing loosening caused by external forces. It also improves flexibility; the different lengths of the connecting feet increase the flexibility of the component, allowing it to adapt to various installation requirements.

[0011] Preferably, the snap-fit ​​plates of the first and second connecting feet are respectively snapped into different slots on the top cover, with the slots located on both sides of the dial hole on the top cover. The slots are positioned at the corresponding locations of the first and second connecting feet on the top cover, with the same tilt angle as the first and second connecting feet. A mounting slot is provided on the other end of the top cover, including a fixing groove. A triangular block is provided at the top of the side wall of the fixing groove to limit the mounting hole of the connecting piece, which is then fixed within the fixing groove of the mounting slot. The cooperation between the snap-fit ​​plates and the slots ensures the stable fixation of the connecting feet within the top cover, reducing loosening. The limiting function is enhanced; the triangular block design ensures stable positioning of the mounting hole of the connecting piece within the fixing groove, improving the reliability of the component.

[0012] Preferably, several connection points are located on opposite sides of the connecting plate of the DIP switch. The DIP switch has several protrusions on one side of the connecting plate, which engage with the DIP switch holes in the top cover. The connecting plate has two protrusions, the distance between which is equal to the width of the DIP switch hole. Each protrusion is a hook-shaped protrusion with an arc-shaped convex bulge on one side. Three grooves are respectively located on both sides of the DIP switch hole. Both the connecting plate and the protrusions are located on the back of the handheld plate. The connecting plate and protrusions are recessed into the DIP switch hole and located inside the top cover, while the front of the handheld plate is located outside the top cover for easy user operation. The handheld plate design facilitates user operation and improves the user experience. The cooperation between the protrusions and grooves ensures the stable fixation of the DIP switch within the top cover, reducing loosening.

[0013] Preferably, the first and second connecting wires are assembled into the wire clip slots of the upper cover via wire clips. The wire clip slots are located at both ends of the upper cover, and the grooves are located on both sides of the DIP switch holes on the upper cover. When the DIP switch is assembled into the upper cover, the protrusions on the DIP switch engage with different grooves on the upper cover, achieving different position limits. The upper and lower covers are snapped together. The wire clip design ensures the stable fixation of the sheathed wires in the upper cover while allowing flexible adjustment of the wire position. The cooperation of the protrusions and grooves ensures the stable positioning of the DIP switch at different positions, improving the reliability of the component.

[0014] Preferably, the connection position of the DIP switch is positioned between and in contact with the first and second connecting pins, and the size of the stop hole is larger than the size of the connection position. Moving the DIP switch simultaneously causes both connecting terminals to move. When the DIP switch is moved to the rightmost position, the connecting terminal of negative circuit 2.3 contacts the connecting piece and conducts, while the connecting terminal of negative circuit 1 does not contact the connecting piece; therefore, the first negative terminal is only connected to negative circuit 2.3. When the DIP switch is moved to the middle position, the connecting terminal of negative circuit 2.3 contacts the connecting piece and conducts, and the connecting terminal of negative circuit 1 also contacts the connecting piece and conducts; therefore, the first negative terminal is connected to both negative circuits 1 and 2. When the DIP switch is moved to the leftmost position, the connecting terminal of negative circuit 1 contacts the connecting piece and conducts, while the connecting terminal of negative circuit 2.3 moves into the stop hole and does not contact the connecting piece; therefore, the first negative terminal is only connected to negative circuit 1. The design of the stop hole and connection position enables multiple conduction states, increasing the functional flexibility of the component. A clearly defined conduction state ensures the stability and reliability of the circuit and reduces the risk of malfunction.

[0015] Preferably, the first positive wire of the first connecting wire and the second positive wire of the second connecting wire are riveted together using copper terminals without flanges, and the connection point between the first positive wire and the second connecting wire is located in the upper cover. This riveting connection method simplifies the assembly process and improves production efficiency.

[0016] The beneficial effects of this invention are as follows: This invention provides a DIP switch assembly that achieves multi-level adjustment without using a printed circuit board by setting a connecting piece and a DIP switch, facilitating maintenance and replacement, and reducing costs. The inclusion of a first connecting pin and a second connecting pin simplifies the structure and enables multi-level adjustment, further reducing manufacturing costs. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In modern electronic devices, DIP switch assemblies are important control components widely used in various devices requiring multi-level adjustment functions. Traditional DIP switch assemblies often rely on printed circuit boards (PCBs) to achieve complex circuit connections and function adjustments. However, this method is not only costly to manufacture but also extremely inconvenient for maintenance and replacement. The DIP switch assembly of this invention innovatively eliminates the reliance on PCBs by incorporating a connecting piece 4 and a DIP switch 5, achieving multi-level adjustment functions while significantly reducing costs and improving the ease of maintenance and replacement.

[0031] In smart home control systems, flexible adjustment of the operating modes and parameters of different devices is required. For example, smart lighting control systems need to adjust parameters such as brightness and color of lights according to different scene requirements. Traditional control methods may use complex electronic circuit boards, which are costly and difficult to repair if a fault occurs. The DIP switch assembly of this invention provides a simple, reliable, and cost-effective multi-level adjustment solution for smart home control systems. In industrial automation equipment, multiple settings for operating parameters are also frequently required, such as motor speed adjustment and equipment operating frequency settings. The emergence of this DIP switch assembly provides a new option for parameter adjustment in these industrial devices.

[0032] like Figure 9 As shown, the connecting piece 4 is fixed to the first negative wire 1.2 of the first connecting line 1 by riveting. This riveting connection method has extremely high stability and reliability. In practical applications, electronic devices are often affected by external forces such as vibration and impact. Traditional connection methods may result in poor contact, leading to circuit failure. The riveting connection ensures that the connecting piece 4 is tightly bonded to the first negative wire 1.2, guaranteeing stable circuit conduction even in harsh working environments. At the same time, the riveting operation is performed directly on the sheathed wire, greatly simplifying the assembly process. On the production line, workers can quickly rivet the connecting piece 4 to the sheathed wire, improving production efficiency.

[0033] like Figure 8 , Figure 9 and Figure 2 As shown, both the first connecting line 1 and the second connecting line 2 are equipped with wire clips 1.3. Wire clips 1.3 consist of two plates connected at the top, which can be secured to the wire clip slots 6.1 of the upper cover 6. Wire clip slots 6.1 are respectively provided at the top of opposite sides of the upper cover 6, and the top of the wire clip slots 6.1 are open. The second connecting line 2 is preferably a three-core sheathed wire, and the first connecting line 1 is preferably a two-core sheathed wire. The multi-core sheathed wire design greatly increases the flexibility of the circuit and can meet different electrical connection requirements. In smart home control systems, it may be necessary to transmit multiple signals simultaneously, such as control signals and feedback signals, which the three-core sheathed wire can easily handle. The design of the wire clips 1.3 ensures the stable fixation of the sheathed wire in the upper cover 6. During equipment handling or use, external forces may pull on the sheathed wire; the wire clips 1.3 effectively prevent the wire from loosening, ensuring the stability of the circuit connection.

[0034] like Figure 7 and Figure 11As shown, the connecting terminal 3 is a cylindrical shell with flanges 3.1 on its sidewalls and openings at both ends, and is preferably a copper terminal. Copper has excellent conductivity, which can effectively improve the transmission efficiency of the circuit. In industrial automation equipment, the stability and speed requirements of circuit transmission are extremely high, and copper terminals can ensure fast and accurate signal transmission. The flanges 3.1 of the connecting terminal 3 are located on the edge of the hole and are inclined outward. The connecting position 5.2 of the DIP switch 5 has a retaining ring near the end of the second connecting line 2. The connecting position 5.2 is an arc-shaped plate that fits the shape of the connecting terminal 3. The diameter of the retaining ring is larger than the diameter of the connecting terminal 3. When the connecting terminal 3 is assembled on the connecting position 5.2, the flanges 3.1 can be locked onto the retaining ring. This design of the flanges 3.1 and the cooperation of the retaining ring ensure the stable fixation of the connecting terminal 3 on the connecting position 5.2. During long-term operation of the equipment, even if subjected to external forces such as vibration, the connecting terminal 3 will not easily loosen, greatly improving the reliability of the circuit connection.

[0035] like Figure 7 As shown, several connection points 5.2 are located on opposite sides of the connecting plate 5.1 of the dial switch 5. The dial switch 5 has several protrusions 5.3 on one side of the connecting plate 5.1; each protrusion 5.3 is a hook-shaped protrusion with an arc-shaped convex bulge on one side. The upper cover 6 has three grooves 6.3, respectively located on both sides of the dial switch hole 6.2, allowing the protrusions 5.3 on the dial switch to engage with the grooves 6.3 in the upper cover 6. The connecting plate 5.1 and the protrusions 5.3 are both located on the back of the handheld plate 5.4, while the front of the handheld plate 5.4 is located on the outside of the upper cover 6 for easy user operation. In actual use, the user can operate the handheld plate 5.4 to move the dial switch 5 to adjust different gear positions. The cooperation between the protrusions 5.3 and the grooves 6.3 ensures the stable fixation of the dial switch 5 within the upper cover 6, reducing the risk of the dial switch 5 becoming loose due to improper user operation.

[0036] like Figure 10 As shown, the connecting piece 4 has a first connecting leg 4.1 and a second connecting leg 4.2, whose tails abut each other, and both are equipped with a locking plate 4.4, which is inclined outward. The first connecting leg 4.1 is longer than the second connecting leg 4.2. The first connecting leg 4.1 is located in the upper half of the connecting piece 4, and the second connecting leg 4.2 is located in the lower half of the connecting piece 4. The abutting tails are provided with mounting holes 4.5 for installation inside the upper cover 6. In actual installation, the design of connecting legs of different lengths increases the flexibility of the component, which can adapt to different installation spaces and needs, and also realizes the adjustment of different positions. The design of the locking plate 4.4 ensures the stable fixation of the connecting legs inside the upper cover 6. When the equipment is subjected to external impact, the locking plate 4.4 can effectively prevent the connecting legs from loosening, ensuring a stable connection between the connecting piece 4 and the upper cover 6.

[0037] like Figure 2As shown, the snap-fit ​​plates 4.4 of the first connecting foot 4.1 and the second connecting foot 4.2 are respectively snapped into different slots 6.4 in the upper cover 6. The slots 6.4 are located on both sides of the dial hole 6.2 in the upper cover 6, and the inclination angle of the slots 6.4 is the same as that of the first connecting foot 4.1 and the second connecting foot 4.2. A mounting position is provided on the other end of the dial hole 6.2. The mounting position includes a fixing groove, and an inverted triangular block is provided at the top of the side wall of the fixing groove to limit the mounting hole 4.5 of the connecting piece 4. The connecting piece 4 is fixed in the fixing groove of the mounting position. The tight fit between the snap-fit ​​plates 4.4 and the slots 6.4 further enhances the fixing effect of the connecting foot in the upper cover 6 and reduces the possibility of loosening. The design of the inverted triangular block ensures the stable limiting of the mounting hole 4.5 of the connecting piece 4 in the fixing groove, improving the reliability of the entire assembly.

[0038] Detailed explanation of the principles of circuit conduction and gear adjustment.

[0039] The circuit conduction and gear adjustment system of this invention adopts an innovative mechanical structure design, realizing precise control of multiple gears and flexible switching of circuit states. The core components of this system include a DIP switch 5, a connecting plate 5.1, a first connecting pin 4.1, a second connecting pin 4.2, and multiple connecting terminals 3. The connecting pin 5.2 of the DIP switch 5 is precisely designed and positioned between the first connecting pin 4.1 and the second connecting pin 4.2, maintaining reliable contact with both. The first connecting pin 4.1 is specially designed with a stop hole 4.3, the size of which is precisely calculated and slightly larger than the size of the connecting pin 5.2. This design ensures reliable contact while providing the necessary space margin for smooth movement of the DIP switch 5.

[0040] In practical implementation, taking a smart home lighting control system as an example, the system adopts a dual-loop design. The second negative wire of the second connecting line 2 contains two independent negative loops: negative loop one 2.2 and negative loop two 2.3. The connection terminals 3 of these two loops are optimized and set on different connection positions 5.2 on the connecting plate 5.1, and the accuracy of switching between each level is ensured by precise spacing control.

[0041] like Figure 2As shown, when the user moves the DIP switch 5 to the far right, the system enters the first gear operating state. At this time, the connecting plate 5.1 extends between the first connecting pin 4.1 and the second connecting pin 4.2. Because the length of the second connecting pin 4.2 is specially designed to be shorter than the first connecting pin 4.1, only the connecting terminal 3 of the negative circuit 2.3 can reliably contact the first connecting pin 4.1. In this state, the connecting terminal 3 of the negative circuit 2.3 forms a conductive circuit through the connecting piece 4, while the connecting terminal 3 of the negative circuit 2.2 remains open. This conductivity method ensures that the first negative electrode is only connected to the negative circuit 2.3, which may correspond to a 30% brightness output mode in a lighting control system.

[0042] like Figure 3 As shown, when DIP switch 5 is moved to the middle position, the system switches to the second position operating state. At this time, the connection terminal 3 of negative circuit 2.3 continues to maintain contact with the first connection pin 4.1, while the connection terminal 3 of negative circuit 1.2 also begins to contact with the second connection pin 4.2. This dual contact state allows both negative circuits to conduct simultaneously, forming a complete circuit with both negative circuits 1.2 and 2.3. In lighting control applications, this conduction method may correspond to a 60% medium brightness mode, providing users with a brighter lighting environment.

[0043] like Figure 4 and Figure 5 As shown, when DIP switch 5 is moved to the leftmost position, the system enters the third position working state. At this time, the connection terminal 3 of negative circuit 1 2.2 remains in contact with the connection piece 4 and forms a reliable connection with the second connection pin 4.2. Meanwhile, the connection terminal 3 of negative circuit 2.3 moves into the position hole 4.3. Due to the precise design of the position hole 4.3, the connection terminal 3 of negative circuit 2.3 is disengaged from the first connection pin 4.1, forming an open state. This conduction method ensures that the first negative electrode is only connected to negative circuit 1 2.2, which may correspond to the 100% maximum brightness output mode in the lighting control system.

[0044] Through this innovative design of the position hole 4.3 and connection point 5.2, this invention achieves precise control over multiple circuit conduction states. The switching between each position is smooth and reliable, with stable contact resistance, ensuring the reliability of the system operation. This design not only greatly increases the functional flexibility of the components but also extends the system's lifespan. In practical applications, this multi-position adjustment mechanism can provide users with a more precise and flexible control experience.

[0045] Assembly process.

[0046] I. Positive wire connection assembly.

[0047] First, the connection of the first positive wire 1.1 of the first connecting wire 1 and the second positive wire 2.1 of the second connecting wire 2 is performed. A copper terminal without a flange 3.1 is selected because this design ensures good conductivity while better suiting the riveting connection requirements. The first positive wire 1.1 and the second positive wire 2.1 are aligned, and the copper terminal is placed over the connection point. At this point, professional riveting equipment is used to precisely control the riveting force and position. During the riveting process, the pressure applied by the equipment causes the copper terminal to undergo plastic deformation, tightly wrapping the two positive wires, thereby achieving conductivity between the first positive wire 1.1 of the first connecting wire 1 and the second positive wire 2 of the second connecting wire 2. In actual production lines, to ensure the stability of riveting quality, the riveting equipment is regularly calibrated and maintained.

[0048] II. Assembly and limit setting of dial switch 5 and upper cover 6.

[0049] like Figure 6 As shown, the next step is to assemble the DIP switch 5 with the top cover 6. The DIP switch 5 features a unique design with distinctive raised bulges. Careful alignment is required when assembling the DIP switch 5 onto the top cover 6. The top cover 6 has pre-designed grooves 6.3 at different positions. When the raised bulges on the DIP switch 5 precisely engage with the corresponding grooves 6.3 on the top cover 6, different position limit functions are achieved. This design is similar to a jigsaw puzzle; the correspondence between each raised bulge and groove 6.3 determines the position setting of the DIP switch assembly. In practice, workers use specialized positioning fixtures to ensure that the DIP switch 5 is accurately installed into the top cover 6. The positioning fixture guides the position of the DIP switch 5, reducing misalignment due to human error. This method greatly improves assembly accuracy and efficiency, ensuring that the position limit function of each DIP switch assembly is precisely achieved.

[0050] III. Assembly of the sheath and the top cover 6 After completing the above steps, assemble the first connecting wire 1 and the second connecting wire 2, which have been riveted together, onto the switch assembly cover 6, which already has the DIP switch 5 installed. The switch assembly cover 6 was designed with the assembly requirements of the sheathed wires in mind, and features corresponding slots 6.4 and mounting positions. During assembly, the worker holds the sheathed wire, aligns it with the slots 6.4 and mounting positions on the cover 6, and then slowly presses down on the connecting piece 4. The connecting piece 4 is designed to fit snugly into the mounting positions; when pressed down, the connecting piece 4 firmly embeds into the mounting positions, thus securing the sheathed wire to the cover 6. During this process, it is crucial to ensure the sheathed wire is accurately positioned and free from misalignment or twisting.

[0051] IV. Connect terminal 3 to DIP switch 5.

[0052] Next, the connection steps for connecting terminal 3 and DIP switch 5 are performed. Connecting terminal 3 has a special structure with a flange 3.1 on its side wall, a design that works in conjunction with the connection position 5.2 of DIP switch 5. Two connecting terminals 3 with flanges 3.1 are selected and inserted into their corresponding connection positions 5.2 on the DIP switch 5 connection plate 5.2. During insertion, ensure that the connecting terminals 3 are inserted vertically and with even force until fully inserted. When the connecting terminals 3 are fully inserted, their flanges 3.1 are precisely engaged with the limiting ring of the connection position 5.2. This fit between the flanges 3.1 and the limiting ring, like a mortise and tenon joint, ensures the stable fixation of the connecting terminals 3 on the connection position 5.2.

[0053] V. Assembly of the cable clip 1.3 and assembly of the upper and lower covers like Figure 1 As shown, after the connection terminal 3 is connected to the DIP switch 5, the clips 1.3 of the first connecting wire 1 and the second connecting wire 2 are respectively inserted into the upper cover 6 of the switch assembly. The clip 1.3 is a two-plate structure with a top connection, perfectly fitting the clip slot 6.1 on the upper cover 6. The worker only needs to align the clip 1.3 with the clip slot 6.1 and press gently, and the clip 1.3 will be firmly inserted. The function of the clip 1.3 is to ensure the stable fixation of the sheathed wire in the upper cover 6, preventing the wire from loosening due to external pulling during equipment handling or use. Finally, the lower cover is assembled with the upper cover 6 using clips. The clip design of the lower cover and the upper cover 6 has been carefully optimized to ensure a tight connection while facilitating disassembly and maintenance. During assembly, the worker only needs to align the lower cover with the clip position of the upper cover 6 and press gently. Thus, the finished DIP switch assembly of this patent is assembled.

[0054] like Figure 9 As shown, the first positive wire 1.1 of the first connecting line 1 and the second positive wire 2.1 of the second connecting line 2 are riveted together using copper terminals without flanges 3.1, and the connection point is located in the upper cover. This riveting connection method simplifies the assembly process and improves production efficiency. In actual production, workers can quickly rivet the first positive wire 1.1 and the second positive wire 2.1 together using copper terminals, and then place the connection point in the upper cover, ensuring a neat and stable circuit connection.

[0055] In a certain intelligent temperature control system, multiple temperature adjustment levels are required. Traditional temperature control systems use printed circuit boards (PCBs) to achieve this, which is costly and complex to maintain. By using the DIP switch assembly of this invention, different temperature adjustment levels can be easily achieved by toggling DIP switch 5. In practical use, users can flexibly adjust the operating mode of the temperature control system according to different seasons and usage needs. Furthermore, since this DIP switch assembly does not rely on a PCB, in the event of a system malfunction, maintenance personnel can quickly inspect and replace components such as the connecting piece 4 and connecting terminal 3, significantly shortening maintenance time and reducing maintenance costs.

[0056] Because the DIP switch assembly of this invention does not use a printed circuit board, the connections between components are clear and simple, offering significant advantages in after-sales maintenance and replacement. When a component malfunctions, maintenance personnel can quickly identify and replace the faulty component. For example, if connection terminal 3 experiences poor contact, maintenance personnel can directly remove connection terminal 3 from connection position 5.2 of the DIP switch 5 and replace it with a new connection terminal 3, making the entire maintenance process simple and quick. Compared to traditional DIP switch assemblies that rely on printed circuit boards, the assembly of this invention significantly reduces after-sales maintenance costs and time.

[0057] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
