The upper elastic piece 51 The other end is connected to the base 1 . Specifically, in this embodiment, the upper elastic piece 51 is placed transversely on the side of the guide core 3 , and the middle portion of the upper elastic piece 51 is located in the side slot 31 . Meanwhile, the lower elastic piece 52 is longitudinally arranged at one end of the upper elastic piece 51 .

In this embodiment, the material, elastic coefficient, thickness, etc. of the upper elastic sheet 51 and the lower elastic sheet 52 can be selected according to specific needs. Preferably, the materials of the upper elastic sheet 51 and the lower elastic sheet 52 in this embodiment are SUS301 stainless steel, that is, stainless steel Shrapnel, elastic coefficient: 1906N/mm ² , thickness 0.05mm, is a general-purpose material, and has the characteristics of high elasticity and long service life.

Tensile experiments were carried out on the stainless steel shrapnel, and the parameters obtained are as follows:

Hardness: 505HV;

Density: 7.93g/cm ³ ;

Tensile strength: 1422N/mm;

Yield strength: 1275N/mm;

Elongation: 7%;

Longitudinal elastic modulus (20°C): 193 KN/mm ² .

Using the above-mentioned stainless steel shrapnel as the upper shrapnel 51 and the lower shrapnel 52 can not only ensure that the upper shrapnel 51 can make a sound when hitting the key switch guide core, but also reduce the direct impact force on the guide core.

In this embodiment, in the process of pressing the guide core 3 to move up and down, the elastic sound-emitting component 5 can achieve a sound-emitting effect. The specific pressing sound principle is:

As shown in FIG. 10 , the key switch is in a natural unpressed state, and the upper elastic piece 51 is in a straight state when it is not assembled. The lower shrapnel 52 is pressed inward by elastic force to become the upper bow shape. At this time, the middle of the upper elastic piece 51 is located in the side notch 31 on the side of the guide core 3, and the upper elastic piece 51 is in a free installation state.

As shown in FIG. 11 , press the guide core 3 downwards, so that the stopper 33 located at the upper end of the side slot 31 exerts a downward force on the upper elastic piece 51, so that the upper elastic piece 51 becomes a straight state. Pushing the lower elastic piece 52 causes the longitudinal elastic piece 522 and the connecting elastic piece 523 on the lower elastic piece 52 to bounce outward to produce deformation. At this time, the upper elastic piece 51 is just in contact with the stopper 33 at the upper end of the side slot 31, and the upper elastic piece 51 is in a state of being flattened and straightened downward.

As shown in Fig. 12, continue to press the guide core 3 downward, the upper elastic piece 51 continues to descend as the lower elastic piece 52 quickly rebounds inwardly, so that the upper elastic piece 51 quickly bounces downward under the action of the force, and moves toward the side. The block 33 at the lower end of the notch 31 hits and makes a sound. At this time, the upper elastic piece 51 changes from a straight state to a downwardly curved state. At this time, the upper elastic piece 51 is in a state of bouncing downward and making a sound.

As shown in FIG. 13 , release the pressing force on the guide core 3 , and the guide core 3 moves up under the action of the elastic restoring force of the elastic member 4 , prompting the stopper 33 located at the lower end of the side slot 31 to exert an upward force on the upper elastic piece 51 , so that the upper elastic piece 51 quickly rebounds back to the straight state, and at the same time, pushes the lower elastic piece 52 to the side, so that the longitudinal elastic piece 522 and the connecting elastic piece 523 on the lower elastic piece 52 bounce outward to produce deformation. At this time, the upper elastic piece 51 is in an upwardly restored straight state.

As shown in FIG. 14 , as the guide core 3 continues to move upward, the lower elastic piece 52 quickly rebounds inwardly, so that the upper elastic piece 51 quickly bounces upward under the action of the force, toward the stopper 33 at the upper end of the side slot 31 . Hit and make a sound. At this time, the upper elastic piece 51 changes from a straight state to an upwardly curved state, that is, the upper elastic piece 51 is in a state of rebounding upward and making a sound.

During the whole process, the up and down movement of the guide core 3 drives the upper shrapnel 51 and the lower shrapnel 52 to act simultaneously. When the upper shrapnel 51 goes down, it hits the block 33 at the lower end of the side notch 31 to make a sound, and when the upper shrapnel 51 goes up, it hits the side notch 31. The stopper 33 at the upper end emits a sound, so the whole process is to sound once for each of the pressing down and the popping up, for a total of two times.

In this embodiment, the stroke of the guide core 3 under the action of the downward pressure and the elastic force of the elastic member 4 (spring) is the same as the movement stroke of the upper elastic piece 51 (the distance between the highest point of the upward bending and the lowest point of the downward bending), preferably 10, the height h1 of the side notch 31 (the distance between the upper end block and the lower end stop of the side notch 31) is less than the height h2 of the upper elastic piece 51 bent. In this way, in the process of moving up and down the guide core 3, the upper elastic piece 51 will hit the block 33 on the side notch 31 to make a sound, and the upper elastic piece 51 can generate enough elastic force to hit the side notch 31 up and down. The end stop 33 produces a louder sound.

As shown in FIG. 5 and FIG. 9 , a positioning pin 35 is extended downward at the lower end of the guide core 3 , and an annular escape groove 36 is formed on the periphery of the positioning pin 35 ; A guide post 12 is provided, and a guide slot 121 into which the positioning pin 35 is inserted is recessed on the upper end of the guide post 12 . As shown in FIG. 16 , the elastic member 4 is a spring. The upper end of the spring is sleeved on the periphery of the positioning plug 35 , and the lower end is sleeved on the periphery of the guide post 12 to provide elastic force for the guide core to rebound. In this embodiment, the elastic force of the spring is 50±10 gf, and the stroke of the guide core 3 from the downward pressing to the upward springing is 4.3 mm.

In this embodiment, the key switch further includes a mechanical conduction component 6 inserted on the base 1 . As shown in FIG. 15 , the mechanical conduction component 6 includes a moving piece inserted into the base 1 . 61, and a static piece 62 inserted on the base 1 and located on the inner side of the moving piece 61, a moving contact is arranged on the side of the moving piece 61, and a side corresponding to the moving contact is arranged on the side of the static piece 62 a static contact; a convex hull 612 is protruded on the side of the moving piece 61 close to the guide core 3 , and a pressing bump 34 corresponding to the convex hull 612 is disposed on the side of the guide core 3 .

The conduction principle of the mechanical conduction assembly 6 in this embodiment is: when the non-pressed state is in the state, the pressing bump 34 on the side of the guide core 3 is just located on the inner side of the convex hull 612 on the side of the moving piece 61, The external extrusion pushes the convex hull 612, so that the moving piece 61 is deformed outward as a whole, then the moving contact on the moving piece 61 is separated from the static contact on the static piece 62, and the key switch is in an off state; when the guide core is pressed 3. When moving down, the pressing bump 34 moves down along with it. When the pressing bump 34 moves down below the convex hull 612 of the moving piece 61, the pressing force of the pressing bump 34 to the convex hull 612 disappears, and the moving piece 61 rebounds, so that the moving contact on the moving piece 61 and the static contact on the static piece 62 re-contact, and the key switch is in the conducting state.

In this embodiment, the key switch also has an intermediate light-emitting function. As shown in FIG. 16 , the guide slot 121 penetrates through to the lower end surface of the base 1 , and directly below the guide slot 121 is an electrical connection to the PCB board. 8 of an LED light. The light emitted by the LED lamp 8 passes through the guide slot 121 and then diffuses out in the direction of the central axis of the guide core 3 to achieve an intermediate lighting effect.
