Vacuum interrupter contact structure and method of fabrication

摘要

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.
