ABSTRACT:
In order to provide a contact preopening of two spring legs of a contact spring, at least one spring leg is provided in a contact zone with a cusp in the form of a protrusion pointing to the other spring leg in the region of at least one long edge. The cusp is formed by embossing, without cutting through material, so as not to create free cut edges that would be vulnerable to corrosion, and so as to prevent the introduction of a plug contact from being impaired by skewed contact preopening spacer elements.
