Hyper thin tactile keyboard assembly

Abstract

The invention relates to a tactile keyboard assembly providing at least one key and constructed on a plurality of foil layers stacked one upon the other, with one layer thereof composed of a dome layer having for each key an elastically deformable dome positioned underneath the respective key. For providing a new and improved structure of a such tactile multi-layered foil keyboard assembly enabling an effective reduction of the thickness, the invention proposes a tactile keyboard assembly for an electronic device, the assembly is constructed on a plurality of foil layers stacked one upon the other and providing the basic structure for at least one tactile key, with one layer of the plurality of layers composed of a dome layer (120, 125) having an elastically deformable dome (125) for each key, and with each dome (125) positioned underneath a respective user area for the key actuation such that the surface of the dome (125) is forming a convex surface with regard to the user area for the key actuation.
