1. the keyboard of a flexible glue and hard sheet integrated injection molding, it is characterised in that:

  • integral type button cap that this keyboard is only made up of flexible glue and hard sheet, button grid support, be positioned at the printed circuit film below integral type button cap and be supported on printed circuit film under keyboard board form;

    The integral type button cap of described flexible glue and hard sheet composition penetrates hard sheet through hole downwards by some adjacent flexible glue key faces hard sheet bonding with flexible glue key face, flexible glue base, the flexible glue supporter being connected between flexible glue base and flexible glue key face and flexible glue key face and the flexible glue convex elastic switch body that is connected as one with flexible glue key face bottom surface forms, and described integral type button cap passes through mould once injection moulding by flexible glue and hard sheet;

    After assembling, button grid support was pressed on the printed circuit film below flexible glue base and flexible glue base after wearing some corresponding flexible glue key faces of integral type button cap by some square through holes of this button grid support, and mutually pressed from both sides with keyboard board and close and fixing button cap and printed circuit film;

    When the flexible glue key face of finger presses key cap, flexible glue key face along with flexible glue supporter bending downwards and move downward vertically, the flexible glue convex elastic switch body being connected as one with flexible glue key face bottom surface also moves until clicking and contacting and make closing of circuit be energized on circuit switching point that printed circuit film is corresponding simultaneously vertically downward;

    When pointing the flexible glue key face leaving key cap, flexible glue convex elastic switch body and flexible glue supporter recover deformation simultaneously, the flexible glue convex elastic switch body circuit switching point corresponding with printed circuit film is separated and breaking circuits, and integral type button cap recovers original state.
