A contact assembly (100, 200, 300, 400, 500, 600) for a vacuum switching apparatus (2) includes a contact member (102, 202, 302, 402, 502, 602) and a reinforcing member (104, 204, 304, 404, 504, 604) adapted to structurally reinforce the contact member (102, 202, 302, 402, 502, 602). The contact member (102, 202, 302, 402, 502, 602) includes first and second opposing sides (106, 306; 108, 308), and a contact thickness (110, 310). The reinforcing member (104, 204, 304, 404, 504, 604) has a reinforcement thickness (112,312), which is less than the contact thickness (110, 310). The contact member (102, 202, 302, 402, 502, 602) is made from a first material having a first coefficient of thermal expansion, and the reinforcing member (104, 204, 304, 404, 504, 604) is made from a second different material having a second coefficient of thermal expansion. The first coefficient of thermal expansion is substantially the same as the second coefficient of thermal expansion. |
