[0002] Tactile switches are commonly used in general electronic components, serving as operating switches on the plug side of devices such as computers, smart washing machines, and air conditioners. Tactile switches with vertical pressing operation are more frequently used. In modern smart appliances, with their increasing functionality, the environments in which they are used vary considerably.

[0003] Most existing tactile switches adopt a vertical pressing structure. In certain specific applications, such as side-triggered remote controls, automotive central control systems, and wearable devices, the traditional structure cannot meet the requirements of installation space and operation direction. Therefore, side-press tactile switches have emerged. However, existing side-press tactile switches still have the following shortcomings: Existing card terminals are often fixed to the base through a simple fitting method, lacking an effective anti-pull structure. They are prone to loosening or falling off during assembly or use, affecting electrical performance and structural reliability; some products require bending the pins to achieve the side-insertion structure, which is not only complex and inefficient in processing, but also difficult to fix during tape packaging, easily leading to displacement or poor contact; some existing springs do not have a pre-compression fit design, causing the spring to vibrate when the button is pressed from the side, affecting the user experience and product noise control.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and embodiments: Figure 1-6 The side-press tape structure switch shown includes a bracket 1, a button body 2, a spring 3, a locking terminal 4, and a base 5. The bracket 1 is provided with a base fixing hole 11 and a button fixing hole 12. The button body 2 includes a pressing part 21, a base 22, and a contact 23. The base 5 is provided with a button receiving cavity 51. The button body 2, the spring 3, and the locking terminal 4 are received in the button receiving cavity 51 from top to bottom. The contact 23 corresponds to the middle bubble point 432 of the locking terminal 4.

[0029] The base fixing hole 11 and button fixing hole 12 on the bracket 1 can be precisely matched with the base 5 and button base 22. The pressing part 21 protrudes laterally from the bracket 1. Combined with the matching of the bracket 1 and the base 5, it can effectively meet the lateral triggering requirements. The button contact 23 directly corresponds to the middle bubble point 432 of the card terminal 4. The alignment is accurate, which can ensure that the contact 23 can reliably contact the bubble point and the impedance is stable when it rebounds.

[0030] As one embodiment of this utility model, such as Figure 2 As shown, the bracket 1 includes a top plate 13 and two side plates 14, the top plate 13 being connected to the two side plates 14; the base fixing hole 11 and the button fixing hole 12 are provided on the top plate 13; the side plates 14 are also provided with pins 15 extending in the same direction; the side plates 14 are also provided with a base fixing block 16, which is located inside the side plates 14.

[0031] The base fixing hole 11 and the button fixing hole 12 are concentrated on the top plate 13, so that the positioning of the bracket 1, the base 5, and the button base 22 is more concentrated and unified. The base fixing block 16 set inside the side plate 14 forms an internal locking structure after engaging with the base 5, which further prevents the bracket 1 and the base 5 from slipping relative to each other due to vibration or external force, and ensures that the components maintain a stable fit during long-term use.

[0032] As one embodiment of this utility model, such as Figure 2 and Figure 6 As shown, the card terminal 4 includes a first terminal 41, a second terminal 42, bubble dots, pins, and terminal fixing pins. The bubble dots include two side bubble dots 431 and a middle bubble dot 432. The pins include a left pin 441 and a right pin 442. The terminal fixing pins include a left terminal fixing pin 451 and a right terminal fixing pin 452. The first terminal 41 is provided with two side bubble dots 431, a left pin 441, and a left terminal fixing pin 451. The second terminal 42 is provided with a middle bubble dot 432, a right pin 442, and a right terminal fixing pin 452. The bottom shape of the pin cutting pin is C-shaped.

[0033] The aforementioned card terminal 4 has a bent step for stability after injection molding. The base 5 prevents the card from being pulled loose when cutting the card, making the connection between the card and the base plastic body more stable. The bottom shape of the PIN cutting foot of the card terminal is C-shaped, so that the product can be better fixed on the paper tape after packaging and will not loosen.

[0034] As one embodiment of this utility model, such as Figure 4-5 As shown, the base 5 is provided with a bracket positioning post 52, which is located on the top of the base 5 and is adapted to the base fixing hole 11. The bracket positioning post 52 passes through the base fixing hole 11. The bottom of the base 5 is provided with a bracket mounting groove 55, and the base fixing block 16 is snapped onto the bracket mounting groove 55. The button receiving cavity 51 is provided with a bubble-filling groove, which includes a central bubble-filling groove 511 and a side bubble-filling groove 512. Bubble point grooves 512 are provided on both sides of the middle bubble point groove 511. The middle bubble point 432 is fixed on the middle bubble point groove 511, and the two bubble points 431 on both sides are fixed on the side bubble point grooves 512. The base 5 is also provided with pin holes 53 and terminal fixing holes 54. The pin holes 53 are provided on the left side of the base 5, and the terminal fixing holes 54 are provided on the right side of the base 5. The pins extend out from the pin holes 53, and the terminal fixing pins are fixed in the terminal fixing holes 54.

[0035] The top positioning post is inserted into the bracket fixing hole, and the bottom fixing block is snapped into the mounting groove, forming a double-sided locking mechanism. This ensures that the bracket 1 cannot slide up or down on the base 5, nor will it shift due to vibration or impact, thus improving the overall structural stability.

[0036] The main functions of this utility model are:

[0037] 1. The bracket positioning column and fixing hole, and the fixing block and mounting groove are locked on both sides. The top plate and side plate are of integrated structure, which enhances the bending and torsional resistance and prevents the parts from shifting or falling off due to vibration or impact.

[0038] 2. The bracket, base, and terminals are integrally injection molded and fixed by snap-fit; reducing the number of parts and processes, and shortening assembly time;

[0039] 3. The C-shaped design at the bottom of the pin stabilizes and secures the braided tape; the straight pin eliminates the need for bending.

[0040] 4. The button contacts precisely align with the center and side bubble points, ensuring uniform pre-compression and stable contact impedance; the terminal fixing feet engage with the base holes to prevent pulling, guaranteeing contact stability during long-term use.

[0041] 5. The side pressing part is guided and fixed by the bracket, ensuring consistent operating stroke and controllable pressing force; the spring preload design effectively suppresses side pressing noise.
