In a further embodiment, the silk screen panel is provided with an indicator silk screen pattern at a position corresponding to the light guide plate, and is provided with an annular atmosphere silk screen pattern at a key mark.

In a further embodiment, the light guide plate is made of acrylic, which has strong light transmittance and uniform light conduction.

In a further embodiment, the screen printing panel has light transmittance at the indication screen printing pattern and the annular atmosphere screen printing pattern, and the remaining parts are opaque, making it easier for staff to observe instructions and operate.

In a further embodiment, the dome sheet is made of nickel sheet, so that the dome sheet has good elasticity and conductivity.

The beneficial effects of the utility model are: (1) By adding a flexible FPC circuit board to the surface sticker, the surface sticker can be bent as a whole to better fit curved products, and the use range of the surface sticker is increased; (2) By adding a flexible FPC circuit board to the surface sticker, The panel, key components and indicating components are integrated in the design, and the silk screen panel and the flexible FPC circuit board are bonded to the PC board through adhesive materials to make it a sealed body, so that the contacts of the dome chip are not affected by the external environment. Interference, not easy to corrode and oxidize, prevent dust pollution at the same time, can be used in various harsh environments. (3) Compared with the existing ordinary face patches, ordinary face patches need to be matched with traditional mechanical buttons. The buttons need to be welded during installation, and even need to be matched with a fixed bracket. The flexible face patches are pasted with adhesive materials and only need to be removed. The adhesive paper can be firmly pasted on the surface of the whole machine, and its leads are inserted into the control board, and the circuit can be connected instantly, saving labor and materials, and reducing the supporting cost of the whole machine.

Detailed ways

In the following description, numerous specific details are given in order to provide a more thorough understanding of the invention. However, it will be apparent to one skilled in the art that the present invention may be practiced without one or more of these details. In other examples, some technical features well known in the art are not described in order to avoid confusion with the present invention.

As shown in Figures 1 to 2, an integrated flexible surface patch includes a panel, key elements and indicating elements. It is an operating system that integrates key functions, indicating elements and panels.

The panel includes a silk screen panel 1, a PC board 2 and a flexible FPC circuit board 3. The silk screen panel 1 and the flexible FPC circuit board 3 are respectively bonded to the upper and lower surfaces of the PC board 2 through adhesive materials and double-sided adhesive. connection method, and the adhesive material can be regarded as an isolation layer. The PC board 2 serves as the main carrier and supports the flexible surface sticker; the designed circuit is etched on the flexible FPC circuit board 3, and the lamp beads 5 are welded to the flexible FPC circuit board 3 through patching.
