Abstract
An electrical contact member and method of fabrication which facilitates braze connection of the electrical contact member to the conductive support stem of a vacuum interrupter structure. A high density slug of the contact material is performed. The high density slug is disposed in a powder mass of the contact material which is sintered to form the contact member. A high conductivity component is then infiltrated in the electrical contact member to produce the desired conductivity for the contact member, with the high density portion being easily brazed to a conductive support stem.
