Abstract

A contact unit, comprising an undivided contact spring (10) with a flexible torsion region (19) between its fixed end and its contact points, is new. A contact unit comprises a stationary contact (12) and a contact spring (10) which has two transverse contact points (15,16) on an undivided spring end section and, between its fixed end and the contact points, a flexible region (19) capable of torsion about its longitudinal axis.
