Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a toggle switch. Background Technology

[0002] DIP switches are common electronic switches widely used in various electronic devices. Traditional DIP switches typically consist of a housing and a circuit board and operating components housed within it. However, with the continuous development of electronic devices, the performance and reliability requirements for DIP switches are becoming increasingly stringent. In current technology, the housing of a DIP switch often simply houses the circuit board and operating components. In some special applications, such as humid environments or equipment requiring high dust and water resistance, traditional DIP switches may not meet the requirements. Furthermore, traditional DIP switches also have limitations in terms of operating feel, reset stability, and lifespan. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a toggle switch that is fully functional, highly adaptable to the environment, and provides an excellent user experience.

[0004] To achieve the above objectives, this utility model employs a toggle switch comprising a housing, a welding cavity formed within the housing, a circuit board welded within the welding cavity, a first mounting groove and a second mounting groove respectively formed on adjacent sides of the welding cavity, a bidirectional rotating support seat installed in the first mounting groove, and a bidirectional magnet rotating support seat installed in the second mounting groove, a magnet installed at the end of the bidirectional magnet rotating support seat facing the circuit board, a flange bushing fitted at the end of the bidirectional magnet rotating support seat with respect to the magnet, and a bidirectional reset torsion spring fastened inside both the bidirectional rotating support seat and the bidirectional magnet rotating support seat to provide a reset force after rotation, and a rocker assembly mounted on the housing.

[0005] The advantages of the above structure are as follows: the compact layout design achieves miniaturization, effectively saving internal space of electronic devices; its bidirectional reset torsion spring ensures stable reset after the switch is turned, improving reliability and service life; at the same time, the switch adopts a magnet and flange bushing design, which enhances environmental adaptability and can operate stably in humid or dustproof and waterproof environments; the user-friendly design of the rocker assembly greatly enhances the user experience, allowing users to operate the toggle switch easily and conveniently, whether for fine-tuning or quick switching, greatly improving the comfort and efficiency of operation.

[0006] This utility model is further configured as follows: the rocker assembly includes a rocker frame, the rocker frame has a mounting cavity at one end corresponding to the housing, a friction block is provided in the mounting cavity, the friction block is located between the rocker frame and the housing, the friction block has at least one friction groove, the friction groove is provided with a friction spring, the rocker frame has a slot at the end away from the housing corresponding to the position where the friction groove is provided on the friction block, a fingertip sleeve is installed on the rocker frame, one end of the friction spring abuts against the friction groove, and the other end abuts against the fingertip sleeve through the slot of the rocker frame. The combination of friction grooves on the friction block and friction springs not only enhances the stability between the rocker arm and the housing, but also, through the elasticity of the friction springs, allows the fingertip sleeve to generate a certain resistance when subjected to external force, effectively preventing accidental operation due to accidental contact. In addition, the slots on the rocker arm and the matching installation of the fingertip sleeves allow users to more intuitively feel the operation feedback of the switch, further improving the reliability and stability of operation. At the same time, the design of the fingertip sleeves also takes ergonomics into account, reducing hand fatigue during long-term use and improving the convenience and comfort of use.

[0007] This utility model further features a rocker arm with a through groove at the end furthest from the housing, connecting to a mounting cavity. A limiting lever assembly is located within this groove. The limiting lever assembly includes a limiting lever positioned within the groove, a transversely penetrating cylindrical pin within the limiting lever, and a lever spring built into the limiting lever. A mounting shaft is provided on the fingertip sleeve. One end of the lever spring abuts against the limiting lever, and the other end abuts against the mounting shaft of the fingertip sleeve. The fingertip sleeve also has a fingertip cap. By adding the limiting lever, cylindrical pin, lever spring, mounting shaft of the fingertip sleeve, and fingertip cap, more precise and stable operation control is achieved. The combination of the limiting lever and lever spring provides stable support and rebound force for the fingertip sleeve, allowing the user to experience clearer and more uniform tactile feedback when operating the toggle switch.

[0008] This utility model is further configured with a housing comprising a base support and a cover mounted on the base support. The combination of the base support and the cover achieves a more robust and reliable structure. The tight fit between the base support and the cover not only effectively prevents the intrusion of external dust, moisture, and other impurities, but also improves the switch's dustproof and waterproof rating, enabling it to maintain excellent performance and stability in harsh environments.

[0009] This utility model is further configured with a waterproof gasket fitted on the bottom housing support. By fitting a waterproof gasket on the bottom housing support, the waterproof performance of the switch is significantly improved. As an additional protective barrier, the waterproof gasket can effectively prevent moisture from seeping into the switch through the gaps in the housing, thereby avoiding malfunctions such as short circuits and component damage caused by moisture intrusion.

[0017] like Figures 1-7As shown, an embodiment of this utility model provides a toggle switch, including a housing 1. The housing 1 has a welding cavity 13 for welding a circuit board (not shown in the figure). The housing 1 has a first mounting groove 14 and a second mounting groove 15 on adjacent sides of the welding cavity 13. A bidirectional rotating support 3 is installed in the first mounting groove 14, while a bidirectional magnet rotating support 4 is installed in the second mounting groove 15. A magnet 41 is mounted on the end of the bidirectional magnet rotating support 4 facing the circuit board 2, and a flange sleeve 42 is fitted onto one end of the magnet 41. The bidirectional rotating support 3 and the bidirectional magnet rotating support 4... The inside of the holder 4 is fitted with a bidirectional return torsion spring (not shown in the figure) to provide a return force after rotation. A rocker assembly 5 is mounted on the housing 1. The rocker assembly 5 consists of a rocker arm 51, a friction block 52, a friction spring 53, a limiting lever assembly 54, a fingertip sleeve 55, and a fingertip cover 56. The rocker arm 51 has a mounting cavity 511 at one end corresponding to the housing 1. A friction block 52 is located inside the mounting cavity 511, between the rocker arm 51 and the housing 1. Friction grooves are formed on the four corners of the friction block 52, and a friction spring 53 is installed in each friction groove. A fingertip sleeve 55 is installed on the rocker arm 51. At the end of the rocker arm 51 furthest from the housing 1, a groove 512 is formed at the position where a friction groove is formed on the friction block 52. This allows one end of the friction spring 53 to rest against the friction groove, and the other end to abut against the fingertip sleeve 55 through the groove 512. Furthermore, at the end of the rocker arm 51 furthest from the housing 1, a through groove 513 is formed, connecting to the mounting cavity 511. A limiting lever assembly 54 is installed within the through groove 513. The limiting lever assembly 54 includes a limiting lever 541 disposed within the through groove 513. A transversely penetrating cylindrical pin 542 is provided within the limiting lever 541. A lever spring 543 is provided, and a mounting shaft 551 is provided on the fingertip sleeve 55. One end of the lever spring 543 abuts against the limit lever 541, and the other end abuts against the mounting shaft 551 of the fingertip sleeve 55. A fingertip cover 56 is also provided on the fingertip sleeve 55. The housing 1 is composed of a bottom housing support 11 and a cover 12 covering the bottom housing support 11. This not only enhances the overall strength and stability of the switch, but also effectively prevents the intrusion of external dust, moisture and other impurities. In particular, the waterproof gasket 111 fitted on the bottom housing support 11 provides an additional protective barrier for the switch, significantly improving its waterproof performance.

[0018] Furthermore, in the design and manufacturing process of the toggle switch in this embodiment, for cases where the friction structure and manual structure do not have a bidirectional reset torsion spring, we can choose to use a unidirectional reset torsion spring and a unidirectional rotation support to meet the requirements. For parts that do not involve reset, we can flexibly choose a unidirectional or bidirectional rotation support to adapt to different application scenarios.

[0019] Of course, in addition to the above embodiments, this utility model may have other various embodiments. Without departing from the essential technical solution of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, and these changes or modifications are equivalent to the technical solution in this patent. Therefore, these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model, and the utility model creation is in line with the applicant's actual R&D capabilities and resource conditions.
