Zusammenfassung: | The invention discloses an integrated touch pressure sensing key structure and a preparation method thereof, the integrated touch pressure sensing key structure comprises a shell, a base and touch plastic, the top end of the base is provided with the shell, two sides of the shell are fixedly connected with heat dissipation structures, the bottom end of the touch plastic is provided with a diaphragm base layer, and the bottom end of the diaphragm base layer is provided with a character printing layer. A circuit layer is installed at the bottom end of the character printing layer, and a pressure sensing mechanism is installed at the bottom end of the character printing layer. The touch plastic and the character printing layer are fixed on the same diaphragm, then the pressure sensor is attached to the diaphragm, the product structure is simplified into one, the display, touch and pressure sensing functions can be achieved, the product design structure can be simplified, and the production cost can be reduced.
