摘要： A contact assembly for an electrical device and a method for making such an assembly are presented. The contact assembly comprises a substrate and a contact material disposed on the substrate. The contact material comprises a composite material comprising a refractory material and a matrix material. The matrix material has a higher ductility than the refractory material. The composite material further comprises a core region and an outer region bounding the core region, the core region having a higher concentration of the refractory material than the outer region. The method applies cold spraying a blended feedstock to produce a layer that includes the composite material described above..

摘要： A blocking member for an actuator having a movable arm for effecting a quick-make feature, includes for example, an elongated member having a first end and a second end, and wherein a portion of said elongated member being configured so that said blocking member disposed in a first position engages a portion of the movable arm of the actuator to restrain movement of the movable arm, and so that said blocking member disposed in a second position disengages from the portion of the movable arm of the actuator to permit movement of the movable arm.
