Abstract
Abstract A printed circuit board capable of resilient deformation having two major surfaces and a contact edge. Electrically conductive traces are provided on each major surface of the board which lead to electrically conductive contact pads at the contact edge of the board. A gap is provided between the two major surfaces of the board along the contact edge. The gap permits resilient deformation of the board so that a force is created upon deformation which will bias the major surfaces toward their undeformed position. An elastomeric biasing member may be provided in the gap.
