[0053] The composition and function of the above embodiment are described in detail as follows: Figures 2 to 5As shown, the key body 24 of the present invention can be made of colloid or plastic material, which can cover and fix the conductive member 25, and the key covering sheet 243 is made of materials including but not limited to glass, plastic, etc.; the conductive member 25 is made of conductive material, and is made of conductive metal material, chemical metal composite material, etc. The conductive member 25 transmits the touch signal to the touch button 2. At this time, the controller of the touch button 2 will calculate the position of the finger 3 and the function represented by the position according to the difference in current change; furthermore, the gasket 26 can be made of soft materials such as silicone, etc., so that it has soft deformation ability, and through its slight adhesive properties, the sensor key 20 can be tightly attached to the touch button 2 of the mobile phone 1. In this way, the user can control the touch button 2 by just touching the surface of the sensor key 20, achieving convenient and practical effects.

[0054] The outer frame 21 can be made of plastic material, and the support ring 22 can be made of hard materials such as metal, glass, sapphire, etc., but not limited to this, so that the outer side 231 of the elastic sheet 23 can be firmly assembled on the support ring 22 without falling off; and the elastic sheet 23 is made of elastic metal or plastic material, so that it can be elastically deformed by external force and can restore its shape when the external force is released. In this way, the user can apply force to press the sensor key 20, so that the sensor key 20 presses against the touch button 2. By filling the sensor key 20 with the plurality of conductive members 25, the sensor key 20 has excellent rigidity and can accurately transmit the pressure value to the touch button 2, so that the touch button 2 senses the user's pressing time, force and size, etc. to trigger the operation function.

[0055] In a preferred embodiment of the present invention, the plurality of conductive members 25 are arranged at equal intervals so as to be evenly distributed on the sensor key 20, and when the finger 3 touches any position on the surface of the sensor key 20, it can correspond to one end of the plurality of conductive members 25. In this way, more touch signals of the finger 3 can be transmitted to the touch button 2 to improve the accuracy of the touch sensing, and at the same time, the ability of the key body 24 to resist deformation can also be improved.

[0056] like Figure 5 As shown, when the finger 3 presses the key body 24 of the sensor key 20, the elastic sheet 23 is deformed to make the key body 24 sink. The edge of the key body 24 does not rub against the support ring 22 during the pressing process to cause obstruction, and the pressure of the finger 3 is transmitted to the touch button 2 through the conductive member 25. The conductive member 25 is made of a non-elastic deformable material, so the pressing force can be transmitted more accurately. At the same time, it is easier for the user to control the pressing force, thereby achieving the purpose of easy operation.

[0057] Furthermore, if the touch button 2 is disposed on the back of the mobile phone 1 (for example, for adjusting the focus when the camera is activated), according to the technology of the present invention, the sensor key 20 can also be disposed on the back panel 11 at a position corresponding to the touch button 2 .

[0058] In addition, according to the technology of the utility model, it is also possible to implement Figure 6 The support ring 27 is configured to have any two oppositely positioned embedding grooves 271 on its inner circumference, the sensor key 20 is configured to have two flat plate-shaped elastic sheets 28, and the key body 29 is configured to have two outer grooves 291 on its outer circumference corresponding to the positions of the two embedding grooves 271, one edge of each elastic sheet 28 is respectively embedded in each embedding groove 271, and the other opposite edge is respectively embedded in each outer groove 291, so that the key body 29 is fixed on the support ring 27. In other words, the elastic sheet 28 is arranged in sections, so that the key body 29 can also achieve the purpose of being elastically pressed.

[0059] The above-mentioned embodiments are only preferred embodiments for fully illustrating the present invention, and are not intended to limit the features of the present invention. Any re-creation using the technical means and creation principles related to the present invention still falls within the scope of the equivalent structural creativity of the present invention.
