Abstract
A contact sheet for providing an electrical connection between two or more electronic devices each having spherical or planar terminals is provided. The contact sheet includes a plurality of insulative elastic substrate sheets having a plurality of through holes formed therethrough and a plurality of conductive elastic contacts each having a first end interposed and fixed between two of the insulative elastic substrate sheets at a fixed point proximate an edge of a respective through hole, and a second end arranged to bend as a cantilever extending from the fixed point. Each contact also includes a centrally located bending portion. The width of the contact continuously varies to be greater at portions of the contact which are subjected to larger stresses and less at positions of the contact which are subjected to smaller stresses when a load is applied to the second end of the contact.
