A contact assembly for use in a vacuum interrupter includes a contact disc of a first electrically conductive material, a coil, and a contact support. The coil is made from a second electrically conductive material and includes multiple helical sections that are oriented axially with respect to a common central axis. Each of the helical sections includes a proximal end and a distal end such that each of the helical sections is connected at the proximal end to a base made from the second electrically conductive material and is connected at the distal end to the contact disc. The contact support is centered axially within the coil and extends from the base to the contact disc.
