- 8 - NICKEL-BASED ELECTRICAL CONTACT DEVICE Abstract This invention relates to a device having an electrically conducting member having a contact surface consisting of a nickel-based contact material. In accordance with the invention, the nickel-based material at least in a surface region (e.g. 23) comprises controlled amounts of hydrogen and has low electrical contact resistance even after prolonged exposure to an oxidizing ambient. When used as a surface layer (e.g. 22) on an electrically conducting member (e.g. 21), such material is suitable as a contact material and represents an inexpensive alternative to gold. And, when prepared in the form of microscopic flakes, such material is suitable for use in electrically conductive inks and adhesives. (FIG. 2)
