Abstract
A contact spring is formed of a strip of spring sheet metal which is divided at one end into at least two and preferably three parallel webs, the two outer webs being longer and bent-back in a U-shape and connected at their free ends to one another by a cross piece which is immediately the U-shaped bend. The cross piece realizes a first contact surface while the shorter middle web has its free end residing opposite the cross piece to form a second contact surface. In the nonbent condition, the contact surfaces lie in the same region and are closely adjacent one another so that a band of spring sheet metal which includes a precious metal layer at only one side in a narrow region of the contact surfaces can be used to manufacture the contact springs. When two webs are provided, a longer one has a transverse arm and is bent-back adjacent the end of the shorter web.
