Abstract
A contact arrangement is provided, e.g. of the type that functions as a wiping contact for a moving contact such as a pivotally mounted switch blade in an electrical power distribution switch. The contact arrangement in an illustrative embodiment includes spaced apart contact members that are biased toward each other to define predetermined contact pressure/force characteristics with respect to the interposed moving contact. The contact members in a preferred embodiment include predetermined contact areas and predetermined structural features to minimize deformation due to magnetic forces experienced in the presence of high currents. The structural features are also arranged to define current paths that increase the contact pressure. In a particular embodiment the contact areas are formed on the contact members so as to minimize the size of the moving contact.
