摘要	A tabulator keyboard of simplified design may be fabricated from a single flexible circuit and a minimum of other mechanical structures. The flexible circuit combines in one piece an array of deformable upper contacts, an array of stationary lower contacts, as well as the required interconnections between the elements of these arrays and the electronics module. The flexible circuit may be made of a reasonable transparent dielectric film (e.g. polyamide). The flexible circuit is folded in use such that the lower stationary array has its conductive surface opposite the upper deformable array. Means are provided for making electrical contact between a selected element in said lower array with a selected element in said upper array.
