Through combining together by the elastic sheet 531 in the elastic component 53, hunch shell fragment 532 and switch on contact piece 533, provide and press down the effect that the elasticity restoring force, still play the drive and switch on the contact point and reciprocate in order to realize switching on and breaking off the function, whole pressing process, each structure action is smooth and easy accurate, switches on and breaks off the function accuracy height.

Specifically, when the guide core 4 is not pressed, the entire elastic member 53 is in a natural state, and at this time, the conductive contact piece 533 and the second conductive terminal 52 are in a separated state, and the first conductive terminal 51 and the second conductive terminal 52 are in an off state, so that the micro switch is in an off state.

When the guide core 4 is pressed downwards, the guide core 4 acts on the elastic piece 531 of the elastic assembly 53, the elastic piece 531 receives the downward acting force of the guide core 4, and receives the upward lifting acting force of the arched elastic piece 532, the arched elastic piece 532 receives the downward acting force of the elastic piece 531, under the mutual acting force, the elastic piece 531 generates downward elastic deformation, and presses the arched elastic piece 532 downwards to make it generate elastic deformation, meanwhile, the downward elastic deformation of the elastic piece 531 can drive the conduction contact piece 533 to move downwards, so that the conduction contact piece 533 is contacted with the second conduction terminal 52, then the first conduction terminal 51 and the second conduction terminal 52 are in a conduction state, and therefore, the micro switch is in a conduction state.

When the pressing on the guide core 4 is released, the elastic restoring force of the elastic piece 531 and the arching elastic piece 532 resets upward and drives the conducting contact piece 533 to move upward, so that the conducting contact piece 533 is separated from the second conducting terminal 52, and the first conducting terminal 51 and the second conducting terminal 52 restore to the off state again, so that the micro switch is in the off state.

In this embodiment, as shown in fig. 1, the first conducting terminal 51 has a first connecting portion 511 and a second connecting portion 512 located above the base 1, an outer side of the first connecting portion 511 is formed with a first slot 5111, and an outer side of the second connecting portion 512 is formed with a second slot 5121; a first opening 5311 through which the first connecting portion 511 passes and a second opening 5312 through which the arching resilient tab 532 arches upward are formed in the resilient tab 531, an inner wall of the first opening 5311 of the resilient tab 531 is clamped into the first clamping groove 5111, a tail end of the arching resilient tab 532 is clamped into the second clamping groove 5121, and a head end of the arching resilient tab 532 upwardly supports the resilient tab 531. Therefore, the elastic piece 531 and the arched elastic piece 532 are integrally erected and limited on the first connecting portion 511 and the second connecting portion 512 of the first conduction terminal 51, so that when the guide core 4 is pressed, the elastic piece 531 and the arched elastic piece 532 can be elastically deformed accurately, and the accuracy of conduction and disconnection work is improved.

Specifically, the arching spring plate 532 is formed by arching the inner wall of the second opening 5312 of the elastic plate 531 upwards, and the conducting contact plate 533 is formed by extending downwards the inner wall of the second opening 5312 of the elastic plate 531. Since the arching spring plate 532 is formed by arching upwards and the conducting contact plate 533 is formed by extending downwards, when the elastic plate 531 moves up and down due to elastic deformation caused by compression, the arching spring plate 532 can elastically deform above the elastic plate 531, and the conducting contact plate 533 moves down below the elastic plate 531, so that the arching spring plate 532 and the conducting contact plate 533 do not interfere with each other and play roles respectively.

In order to further avoid interference, the head end of the arching elastic sheet 532 is integrally connected with the elastic sheet 531 by two elastic strips 5321; the end of the conductive contact 533 connected to the elastic piece 531 is located between the two elastic strips 5321. Therefore, the connection ends of the arching spring plate 532 and the elastic plate 531 and the connection ends of the conducting contact plates 533 and the elastic plate 531 extend up and down separately, the structural design is reasonable, interference caused by mutual action is further avoided, and accuracy of each structural action is provided.

When the conductive contact 533 moves down, the movable contact 5330 can better and more directly contact the arched contact portion 520, thereby improving the accuracy of the conduction.

Thus, the free switching between pressing with sound and pressing without sound is realized.

In the present embodiment, the on-contact point of the on-mechanism 5 is separated from the switching type silent audible mechanism 6, that is, the on-contact point is separated from the switching type silent audible mechanism 6, so that the space design is reasonable, the mutual interference between the on-contact point and the switching type silent mechanism is avoided, and the accuracy of the on-off function and the switching type silent switching function is improved.

In the present embodiment, as shown in fig. 1, fig. 4 and fig. 6, the toggle switching element 62 includes a rotation mounting base 621 rotatably disposed on the upper cover 2 or the base 1, and a toggle handle 622 connected to the rotation mounting base 621 and extending to the outer sides of the upper cover 2 and the base 1, and correspondingly, a side opening 22 for the toggle handle 622 to pass through and toggle is formed on the upper cover 2 or the base 1, as shown in fig. 2.

Specifically, the rotating mounting seat 621 of the present embodiment is rotatably disposed on the base 1, but may also be rotatably disposed on the upper cover 2. By dialing the dial 622, the rotation mounting seat 621 rotates to drive the upper soft part 63 and the lower soft part 64 to rotate, so that the upper soft part 63 and the lower soft part 64 are switched between approaching the elastic sheet 531 and leaving the elastic sheet 531, and the free switching function of sound pressing and soundless pressing is realized.

In the present embodiment, the upper soft portion 63 and the lower soft portion 64 have soft, flexible and elastic characteristics, so that when the elastic sheet 531 acts on the upper soft portion 63 and the lower soft portion 64, the purpose of noise reduction is achieved, and the effect of silence is achieved. The upper soft portion 63 and the lower soft portion 64 can be made of silicone.

In order to generate the toggle hand feeling, in this embodiment, a limiting elastic sheet 65 located on one side of the lower portion of the rotating installation seat 621 is disposed on the base 1, a limiting protrusion 651 is convexly disposed on one side of the limiting elastic sheet 65 close to the rotating installation seat 621, and two limiting grooves 6213 matched with the limiting protrusion 651 are formed on one side of the lower portion of the rotating installation seat 621. Stirring and dialling handle 622, when driving and rotating mount pad 621 and rotating, rotating the mount pad 621 outside and acting on spacing arch 651 of spacing shell fragment 65, because spacing arch 651 can take place elastic deformation for rotate the mount pad 621 outside and can take place interact with spacing arch 651, thereby produce and stir and feel. Meanwhile, after the button is pushed to the right position, the limiting bulge 651 is clamped into the limiting groove 6213, so that the functions of limiting, positioning and preventing shaking are achieved, and the accuracy of sound pressing and silent switching is improved.

In the specific installation, as shown in fig. 6, in this embodiment, a mounting groove 11 for installing the lower portion of the rotating installation seat 621 is formed on the base 1, a limiting clamping groove 12 for embedding the limiting elastic sheet 65 is formed on one side of the mounting groove 11, a central rotating shaft 13 is disposed on the mounting groove 11, and the rotating installation seat 621 is rotatably sleeved on the central rotating shaft 13. By the combination of the mounting groove 11, the limiting clamping groove 12 and the central rotating shaft 13, the rotating mounting seat 621 and the limiting elastic sheet 65 can be stably mounted on the base 1, and the effect of the rotating mounting seat is accurately exerted.

In the present embodiment, as shown in fig. 1 and 5, a side limiting opening 611 is formed on the sounding and striking block 61, an upper striking sounding part 612 is formed at the upper end of the side limiting opening 611, and a lower striking sounding part 613 is formed at the lower end of the side limiting opening 611; one end of the elastic piece 531 passes through the side limiting opening 611, the upper tapping sound-emitting portion 612 is located above one end of the elastic piece 531, and the lower tapping sound-emitting portion 613 is located below one end of the elastic piece 531. Meanwhile, as shown in fig. 1 and 5, the sounding striking block 61 is disposed on the base 1 through a connection terminal 610.

When the elastic piece 531 moves up and down, the upper tap sound emitting unit 612 and the lower tap sound emitting unit 613 are directly tapped to emit sound.

In order to switch between the pressing sound and the soundless sound, as shown in fig. 5 and 6, the distance between the upper tapping sound-emitting portion 612 and the lower tapping sound-emitting portion 613 is greater than the distance between the upper soft portion 63 and the lower soft portion 64. Thus, when the upper and lower

flexible portions

63 and 64 rotate to the upper and lower sides of the elastic piece 531, the up-and-down movement of the elastic piece 531 directly acts on the upper and lower

flexible portions

63 and 64 without contacting the upper and lower click sound generating portions 612 and 613, thereby realizing the pressing soundless function.

The second embodiment:

the main difference between this embodiment and the first embodiment is that the structure of the elastic component is different. In the present embodiment, as shown in fig. 7 and 8, the conducting contact 533 of the elastic component 53' is integrally connected to the elastic piece 531, and the head end of the arching spring piece 532 extends to the lower end of the elastic piece 531 and abuts against the lower end surface of the elastic piece 531, so that the arching spring piece 532 is limited between the second connection portion 512 of the first conducting terminal 51 and the elastic piece 531.

Specifically, the conducting contact piece 533 is formed by extending downward an inner wall of the second opening 5312 of the elastic piece 531, two first abutting blocks 5313 are formed on the inner wall of the second opening 5312 of the elastic piece 531, the first end of the arching elastic piece 532 has two first abutting strips 5322 abutting against the lower ends of the two first abutting blocks 5313, and the end of the conducting contact piece 533 connected to the elastic piece 531 is located between the two first abutting strips 5322.

Since the arching spring plate 532 is formed by arching upwards and the conducting contact plate 533 is formed by extending downwards, when the elastic plate 531 moves up and down due to elastic deformation caused by pressure, the arching spring plate 532 can elastically deform above the elastic plate 531, and the conducting contact plate 533 moves down below the elastic plate 531, so that the arching spring plate 532 and the conducting contact plate 533 are not interfered with each other and can respectively play a role. Meanwhile, the abutting ends of the arched spring plate 532 and the elastic plate 531 and the connecting ends of the conducting contact plates 533 and the elastic plate 531 extend up and down separately, the structural design is reasonable, interference between the arched spring plate and the elastic plate is further avoided when the arched spring plate and the elastic plate 531 act, and therefore accuracy of all structural actions is improved.

Example three:

the main difference between this embodiment and the first or second embodiment is that the structure of the elastic component is different. In the present embodiment, as shown in fig. 9 and 10, the head end of the arching spring piece 532 in the elastic assembly 53 ″ extends to the lower end of the elastic piece 531, and is abutted against the lower end surface of the elastic piece 531, and the conductive contact piece 533 is integrally connected to the arching spring piece 532, so that the arching spring piece 532 is limited between the second connection portion 512 of the first conductive terminal 51 and the elastic piece 531.

Specifically, two second abutting blocks 5314 are formed on the inner wall of the second opening 5312 of the elastic piece 531, and two second abutting strips 5323 abutting against the lower ends of the two second abutting blocks 5314 are provided at the head end of the arching elastic piece 532; the conducting contact piece 533 is formed by extending the head end of the arching elastic piece 532 downward, and the end of the conducting contact piece 533 connected with the arching elastic piece 532 is located between the two second contact strips 5323.

Because the arching spring plate 532 is formed by arching upwards, and the conducting contact plate 533 is formed by extending downwards, when the elastic plate 531 moves up and down due to elastic deformation caused by compression, the arching spring plate 532 can elastically deform above the elastic plate 531, and the conducting contact plate 533 moves down below the arching spring plate 532, so that the arching spring plate 532 and the conducting contact plate 533 do not interfere with each other and play roles respectively. Meanwhile, the abutting ends of the arching elastic sheet 532 and the elastic sheet 531, and the connecting ends of the conducting contact sheet 533 and the arching elastic sheet 532 extend separately, so that the structural design is reasonable, interference caused by mutual actions is further avoided, and the accuracy of each structural action is improved.

The above description is only a preferred embodiment of the present invention, and does not limit the technical scope of the present invention at all, so that other structures obtained by using the same or similar technical features as the above embodiments of the present invention are within the protection scope of the present invention.
