Abstract
Abstract A circuit board electrical interconnection system, including improved, elongated, bodily-rotatable interconnect elements, is disclosed. Each element has tab portions projection angularly from the opposing ends of the element, which tab portions define a pair of pad engagement surfaces. The pad engagement surfaces engage corresponding contact pads on opposing surfaces of two circuit boards by means of elastic support member. The element is divided longitudinally, axially or laterally into a plurality of sectors. Some sectors are electrically conductive, while others have other electrically predetermined characteristics. The two types of sectors are arranged in an alternating patter. The non-conducting sectors may be comprised of insulative, resistive or capacitive materials.
