An electrical contact is for a vacuum switching apparatus. The vacuum switching apparatus includes a second electrical contact. The electrical contact includes a body having a center point and a periphery, the body including a plurality of arcing surfaces structured to face in a first direction toward the second electrical contact and structured to move into and out of engagement with the second electrical contact, and a plurality of arc spinning portions each defining a slot extending inwardly from the periphery generally toward the center point, the plurality of arc spinning portions generally separating the plurality of arcing surfaces from one another. At least one arc spinning portion narrows from a corresponding pair of adjacent arcing surfaces of the body to an interior thereof in a second direction opposite the first direction.

Vacuum switching apparatus and electrical contact therefor

A vacuum switching apparatus includes a vacuum envelope; a fixed contact assembly partially within the vacuum envelope; a first movable contact assembly partially within the vacuum envelope; a second movable contact assembly partially within the vacuum envelope; a first bellows within the vacuum envelope and cooperating with the first movable contact assembly to maintain a partial vacuum within the vacuum envelope; and a second bellows within the vacuum envelope and cooperating with the first movable contact assembly and the second movable contact assembly to maintain a partial vacuum within the vacuum envelope.
