Abstract

The present invention relates to a keyboard (10), including at least an upper portion (20a), having first electrical contacts (15) corresponding to respective keys (11) of the keyboard (10), and at least a lower portion (20b), having second electrical contacts (25) that, in use, are positioned opposite said first electrical contacts (15) and at a given distance (d) therefrom. In the keyboard (10), the distance (d) between the first and second contacts (15, 25) is obtained by means of a layer of spacers (27) having a height (h) that can be selectively determined by means of a silk-screen process. In this manner, keyboards with extremely limited overall thickness and distance between the contacts can be manufactured. The invention also relates to a process of manufacturing the keyboard (10).
