The present invention relates to an improved structure of a bracket component for the press button of a mobile phone, more particularly to another improved design implemented in the interior of a printed circuit board having control button on it for a bracket component by using thin membrane touch switch within a mobile phone. The bracket component according to the present invention is a curved metallic guiding bracket wherein the corresponding surrounding.has an inward cut curve, and such cut curve design has a four supporting legs deposed around the aligned design on the printed circuit board allowing a better positioning function. Furthermore, the present invention with the cut curve design has a characteristic to resume the press keys more effectively, and in turn elongate the life of the bracket.
