| 摘要 | A switch apparatus (10) includes a first layer (11) and a second layer (12) attached to one another via sets of fastening elements (13A-13F, 14A-14F) formed on the layers. The fastening elements may comprise hook-like elements that engage one another in an interlocking arrangement to attach the layers, or alternatively, the fastening elements may take other forms. The fastening elements may include flexible portions that flex when the first layer and second layer are forced together. The apparatus may be used within switch arrays, and can eliminate the need for dome spring elements. | ||||||
