[0021] To make the technical content, construction features and effects of the utility model clear, the following will be described in detail in combination with the embodiments and the drawings.

[0022] As shown in Figures 1 to 4 the keyboard switch button 100 of the utility model includes a seat body 1, a key 2 and a compression spring 3, the key 2 is movably arranged in the seat body 1, the compression spring 3 is arranged between the key 2 and the seat body 1 and provides an elastic force for the end of the key 2 to extend out of the seat body 1. The seat body 1 includes a base 11 and an upper cover 12, the upper cover 12 is clampedly connected on the base 11, the upper side of the upper cover 12 is provided with an opening 121 communicating inside and outside, the opening 121 is square, the key 2 extends through the opening 121 and extends out of the upper cover 12. The inner side wall around the opening 121 is provided with a guide rib 122 protruding inward, the guide rib 122 is located at the four corners close to the opening 121. The extension direction of the guide rib 122 is parallel to the central axis direction of the opening 121. The guide rib 122 is in sliding contact with the outer side wall of the key 2. In addition, as shown in Figure 4 the outer side edge of the key 2 can also extend a retaining wall 21 towards the upper side of the opening 121, the retaining wall 21 can limit the upper end of the key 2 and also can protect the cross pressing part on the upper end of the key 2.

[0023] Please refer to Figure 2 and Figure 5The bottom of the key 2 is provided with a containing groove 22, and the inner side wall around the containing groove 22 is provided with a pipe site 23 protruding inwardly. When the compression spring 3 is contained in the containing groove 22, each pipe site 23 is clamped on the outer periphery of the compression spring 3. By arranging the pipe site 23, the upper end of the compression spring 3 can be limited, and the compression spring 3 can be prevented from shaking in the gap of the containing groove 22, so as to improve the stability of the key 2. Moreover, the pipe site 23 can make the compression spring 3 accurately aligned during assembly, so as to improve the convenience of assembly. The bottom of the containing groove 22 is provided with a shaft pipe 24 extending towards the base 11, and the compression spring 3 is contained in the containing groove 22 and sleeved on the shaft pipe 24. By arranging the shaft pipe 24, the compression spring 3 can be guided during compression or expansion, so as to ensure that the compression spring 3 will not be deformed and displaced during work, and the stability is improved, so that the elastic feeling of the key 2 during pressing can be improved. The compression spring 3 is a waist drum type spring, and the diameter of the middle section of the waist drum type spring is larger than the diameters of the opposite two ends. By arranging the compression spring 3 in the waist drum type structure, the compression spring 3 is not easy to be bent during pressing, so that the pressing feeling is more smooth.

[0024] Please refer to Figure 6 The middle part of the base 11 extends towards the key 2 and is provided with a sleeve 111 sleeved on the outer side of the shaft pipe 24. The inner side wall of the sleeve 111 is provided with a guide strip 112 around the central axis, and the extension direction of the guide strip 112 is parallel to the direction of the central axis. The guide strip 112 is in sliding contact with the outer side wall of the shaft pipe 24. By arranging the sleeve 111, the lower end of the compression spring 3 can be positioned, and the lower end of the compression spring 3 and the shaft pipe 24 can be guided. By arranging the guide strip 112 on the inner side wall of the sleeve 111, the shaft pipe 24 can be prevented from loosening during sliding. Moreover, the guide strip 112 can reduce the contact area between the shaft pipe 24, so as to reduce the friction resistance and improve the smoothness of the key 2 during sliding.

[0025] Please refer to Figure 7 The bottom of the base 11 is provided with an exhaust hole 113, and the exhaust hole 113 is in communication with the outside and the inside of the base 1. Since the base 11, the upper cover 12 and the key 2 are assembled to form a relatively closed space, the space between the key 2 and the base 11 will change during pressing of the key 2, and the air pressure will also change. If the gas cannot be discharged during pressing, the key 2 will be blocked, so as to affect the pressing feeling of the key 2. By arranging the exhaust hole 113, the key 2 will not be blocked during pressing, and the bottom sound will be more crisp.

[0026] Please refer to Figure 2The keyboard switch button 100 further comprises a magnet 4 which is built in the shaft tube 24. The magnet 4 can cooperate with a magnetic sensor installed on a keyboard circuit board to generate a signal. One side of the upper cover 12 is provided with a mounting groove 123 in which a light guide column 5 is arranged. The light guide column 5 can make the keyboard switch button 100 have a night light function.

[0027] Compared with the prior art, the guiding rib 122 which is inwardly protruding around the opening 121 of the upper cover 12 can be in sliding contact with the outer side wall of the key 2, so that the periphery of the key 2 can be limited, the stability of the key 2 during sliding can be ensured, and the feeling of shaking or loosening cannot occur, the contact area between the inner side wall of the opening 121 and the outer side wall of the key 2 can be reduced, so that the frictional resistance can be reduced, and the smoothness of the key 2 during sliding can be improved. Furthermore, the pressing effect of the key 2 can be improved by various means such as the pipe site 23 arranged on the key 2, the guiding strip 112 arranged in the sleeve 111 of the base 11 and the exhaust hole 113 arranged at the bottom of the base 11, so that the pressing feeling of the key 2 is very good.

[0028] The above disclosed is only a preferred embodiment of the utility model, of course, cannot with this to limit the utility model right scope, therefore the equivalent change made by the utility model application patent range, still belongs to the utility model covered range.
