  • Abstract
    The authors describe a mechanical design approach for metal armatures which is based on preventing contact arcing. The minimum pressure required to prevent arcing is combined with the mechanical characteristics of the armature to define its safe operating envelope. The design goal is to provide an envelope which will permit armature operation over the range of current and armature deflection expected during launch. The procedure has been used to design successfully a 15-mm armature
