Abstract
A floating contact assembly is provided. The floating contact assembly includes a substantially rigid first conductive member, a flexible conductive shunt, and a substantially rigid second conductive member. The flexible conductive shunt is coupled to, and is in electrical communication with, the first conductive member. The second conductive member is coupled to, and is in electrical communication with, the flexible conductive shunt. In this configuration, the second conductive member “floats” within the first conductive member.
