摘要： A multicontact spring having a number of contacts per unit width is produced by press working. A metal tape for a spring is blanked to form a blank. The blank is pressed to make linear dents and, then, cutting of each one of the linear dents is performed. The blank having the cut parts is deformed to form it into a suitable shape for contact points. The thus produced multicontact spring has cut and deformed parts, i.e. contacts, having no free ends. Thereafter, if desired, one end part of the blank is cut to form another type multicontact spring having contacts which have free ends, respectively.
