Abstract:
A dome array device is disclosed, which includes a film plate, a plurality of metal flexible plates, and a covering layer. The film plate has a first surface and a second surface. A plurality of flexible press portions protrudes from the film plate. The metal flexible plates are respectively located on the second surface of the flexible press portions of the film plate. The covering layer is formed and covered on the first surface of the film plate. A plurality of plungers that respectively corresponds and locates on the flexible press portions protrudes from the covering layer. A plurality of function portions that is located around the flexible press portions extends and protrudes from the covering layer. Furthermore, a key structure with the dome array device is disclosed, and thereby the operation sensitivity is improved, the total thickness is reduced, and the manufacturing cost is decreased.
