Abstract

A method of manufacturing contact structures on a support strap wherein at least one layer of a contact material such as gold, silver or alloys thereof is applied on top of the cross-web of a T-shaped metal strip of an easily cold stampable material and sections of predetermined length are cut from the T-shaped strip thereby providing contact members with stem portions with which they are inserted from one side of a support strap through corresponding openings stamped into the support strap whereupon the stems of the contact members which project through the support strap are stamped from the other side so as to firmly engage the contact members with the support strap. This method permits automatic manufacturing without damage to the contact surface of the contact members when being mounted on the strap.
