The contactor includes an elongated beam having a U-shaped end. Several carbon fibers form a bundle attached to the beam. The fibers have ends and tips. The ends are compressively held inside the U-shaped end and the tips emanate from the U-shaped end. An elastomer is disposed over the carbon fibers where they emanate from the U-shaped end. The elastomer reduces flexing of the carbon fibers. The elastomer is located between the beam and adjacent to the tips with the tips being exposed. A laser is used to trim the carbon fibers and elastomer to form the tips.
