<p>A cylindrical lever (10) is made of a material which is a good electrical conductor. It is tiltably supported in a hole of a first tag. Its flange is pressed by a spring to the tag, and its other end passes with a clearance through a hole in a further tag, as in 26 34 878. The hole (14) in the further tag (5) has at least one contact spring (15), connected with the tag and concentric with its edge.</p> |
