[0006] As a preferred solution of the present invention, the inner button is made of silica gel.

[0007] As a preferred solution of the utility model, a lead-out terminal is installed inside the base, the lead-out terminal is connected to the spring sheet, and one end of the lead-out terminal extends to the outside of the base.

[0008] As a preferred solution of the utility model, a positioning column is fixedly connected to the top of the base, and a through hole matching with the positioning column is opened on the cover plate.

[0009] As a preferred solution of the utility model, buckles are provided on both sides of the cover plate, and a slot matching with the buckles is provided on the bottom of the base.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model has the following beneficial effects: the inner button is provided to isolate and buffer the touch switch; when the touch switch falls, the button cannot directly contact the spring sheet; the inner button can effectively absorb and disperse the impact force of the button, protect the spring sheet, and prevent the button from damaging the spring sheet, thereby causing the touch switch to malfunction, thereby improving its reliability and extending its service life; and the raised portion is provided to make the inner button fit the button more closely, thereby preventing the inner button from being offset; and at the same time, the raised portion can also reduce the contact area between the inner button and the spring sheet, thereby concentrating the pressing force on the raised portion; and thus, only a small force is required to press the button to allow the inner button to deform the spring sheet, thereby making it convenient for people to use.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1 to Figure 2 The utility model provides a technical solution: a light touch switch, including a base 4, a spring sheet 3 is installed inside the base 4, an inner button 6 is installed on the top of the spring sheet 3, the inner button 6 plays an isolation and buffering role, when falling, the button 2 cannot directly contact the spring sheet 3, the inner button 6 can effectively absorb and disperse the impact of the button 2, and play a protective role on the spring sheet 3 to prevent the button 2 from damaging the spring sheet 3. The top of the inner button 6 is provided with a button 2, and the top and bottom of the inner button 6 are integrally formed with a raised portion 11. The raised portion 11 at the top allows the inner button 6 to fit the button 2 more closely and prevents the inner button 6 from shifting. The raised portion 11 at the bottom can reduce the contact area between the inner button 6 and the spring sheet 3, so that the pressing force is concentrated on the raised portion 11. Therefore, only a small force is needed to press the button 2 to allow the inner button 6 to deform the spring sheet 3. A cover plate 1 is installed on the outer side of the base 4. The cover plate 1 is used to limit the button 2 to prevent the button 2 from separating from the base 4. The top of the button 2 extends through the cover plate 1 to the outer side of the cover plate 1.

[0016] Among them, the material of the inner button 6 is silicone, which has excellent elasticity, so that when it falls, the silicone can effectively absorb and disperse the impact force of the button 2, and the silicone is not too soft, and has sufficient hardness to deform the spring piece 3, so that the button 2 does not need to be pressed a large distance to deform the spring piece 3. At the same time, silicone has strong anti-aging properties and a long service life.

[0017] A lead-out terminal 5 is installed inside the base 4 . The lead-out terminal 5 is used to connect to an external wire. The lead-out terminal 5 is connected to the spring 3 , and one end of the lead-out terminal 5 extends to the outside of the base 4 .

[0018] Among them, a positioning column 8 is fixedly connected to the top of the base 4, and a through hole 7 matching the positioning column 8 is opened on the cover 1. The through hole 7 and the positioning column 8 are used to position the cover 1 to ensure that the cover 1 is firmly installed and will not deviate.

[0019] Among them, buckles 9 are provided on both sides of the cover plate 1, and a slot 10 matched with the buckle 9 is provided at the bottom of the base 4. The buckle 9 and the slot 10 cooperate to fix the cover plate 1 on the outer side of the base 4.
