Abstract
Abstract An electrical contact element of the two-fingered spring-like contact type is formed so that the spaced contact fingers are folded along an axis parallel to the fingers and extend normal to the plane of the attaching flange and are also bent about an axis extending between them so that each contact finger forms the arm of a V. A retaining flange is wrapped around the folded contact element to retain the contact fingers in their overlapped relationship.
