Electrical switching apparatus, and crossbar assembly and spring cap therefor

A crossbar assembly for an electrical switching apparatus, said electrical switching apparatus comprising a housing, a number of a stationary contacts, a number of movable contacts, and a number of moving arms, each of said movable contacts being disposed on a corresponding one of said moving arms, said crossbar assembly comprising:

• a crossbar structured to pivot said number of moving arms thereby moving said movable contacts into and out of electrical communication with said stationary contacts, said crossbar having a number of molded recesses;
• a pair of contact springs disposed in each of said molded recesses;
• a spring clip enclosing said pair of contact springs within said molded recess, said spring clip being disposed between a corresponding one of said moving arms and said pair of contact springs;
• and
• a spring cap cooperating with said pair of contact springs within said molded recess, each spring cap comprising:
• a first segment disposed between said spring clip and a first contact spring of said pair of contact springs,
• a second segment disposed between said spring clip and a second contact spring of said pair of contact springs, and
• a connecting portion connecting the first segment to the second segment,
• wherein said spring cap supports said spring clip and evenly distributes bias forces of said first contact spring and said second contact spring.
