Abstract:
A spring contact has a post-release outer upper surface in compression and a post-release outer lower surface in compression. A compressive lower layer of spring material may be formed at a thickness that is three-eighths or less of a tensile upper layer of spring material. A low modulus of elasticity cladding material may also be applied to the outer surface of the spring contact with a lower surface of the cladding material being formed with a compressive stress.
