The crossbar assembly includes a crossbar, a first contact spring, a second contact spring, and a spring clip. The moving arm is coupled to the crossbar. The spring cap includes a first segment structured disposed between the spring clip and the first contact spring, a second segment disposed between the spring clip and the second contact spring, and a connecting portion connecting the first segment to the second segment. The spring clip is disposed between the moving arm and the contact springs. The spring cap supports the spring clip and evenly distribute bias forces of the contact springs.
