Abstract
A contact assembly for a vacuum switching apparatus includes a contact member and a reinforcing member adapted to structurally reinforce the contact member. The contact member includes first and second opposing sides, and a contact thickness. The reinforcing member has a reinforcement thickness, which is less than the contact thickness. The contact member is made from a first material having a first coefficient of thermal expansion, and the reinforcing member 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.
