The pressing action of the key will make the contacts of the mechanical switch close, thereby completing the connection of the circuit and turning on the air conditioning system.
[0003] The automobile air conditioner is frequently used in different seasons and weather conditions. In hot summer, people will frequently turn on and off the air conditioner or adjust the temperature, wind speed and other functions in order to keep the car cool. In cold winter, the warm air function of the air conditioner also needs to be turned on for heating. This high frequency of use will cause the key cap to be pressed constantly, and its mechanical structure and surface material are prone to wear and deformation due to repeated friction and stress. Once damaged, the entire key assembly needs to be replaced, which directly increases the maintenance cost of the user. SUMMARY

The inside of the touch switch is movably installed with a moving contact, and the surface of the moving contact is covered with a switch sheet. The bottom of the switch sheet is fixedly provided with a clamping seat, and the inside of the clamping seat is provided with a positioning groove.
[0006] Preferably, the switch sheet is a circular structure made of plastic material, and the switch sheet covering the surface of the touch switch is a detachable structure.
[0007] Preferably, the surface of the switch sheet is fixedly provided with a stress seat on both sides, and the two groups of stress seats are symmetrical structures about the central axis of the switch sheet.
[0008] Preferably, the two groups of stress seats are arc-shaped, and the top of each group of stress seats is fixedly provided with a stress strip. The cross section of the stress strip and the stress seat is "L" shaped.
[0009] Preferably, the inside of the moving contact is provided with a positioning seat, and the outside of the positioning seat is provided with a clamping groove. The moving contact is square.
[0010] Preferably, the size of the clamping groove and the size of the clamping seat are matched, and the size of the positioning seat and the size of the positioning groove are matched, and the clamping seat is clamped in the inside of the clamping groove, and the positioning seat is inserted in the inside of the positioning groove.
[0011] Preferably, the positioning seat and the positioning groove are both arranged in a "cross" shape, and the height of the positioning seat is equal to the depth of the positioning groove.
[0012] Compared with the prior art, the utility model has the beneficial effects that:
[0013] 1. The utility model discloses a switch piece is covered on the upper surface of the touch switch, the clamping seat is clamped in the inside of the clamping groove, the positioning seat is inserted in the inside of the positioning groove, and the positioning installation work between the switch piece and the touch switch is completed.
