Abstract
A circuit interrupter including separable main contacts, an operating mechanism interconnected with the contacts, and a housing in which the contacts and the operating mechanism are disposed. The housing includes a cover positioned on top of a base, the cover including first contact surfaces for contacting and mating with second contact surfaces of the base. The cover also includes a contact region. The operating mechanism includes a support member that is situated within the base and which has an upper surface with a raised region. The raised region is positioned to make contact with and pierce into the contact region before the first contact surfaces fully mate with the second contact surfaces.
