The contact element, in the known device by a Band is formed from copper braid is made by hand punctiform by means of adhesive or a welded joint attached to the contact surface of the base body. The contact element is in the top view essentially rectangular, in which desired mounting position its longitudinal edges in substantially parallel to adjacent edges of the Basic body run.

A disadvantage of the known device is that the danger of attaching the contact element there is that the contact element slips and is attached to the base body in one position which its longitudinal edges are not parallel, but in undesirable Way obliquely to the edges of the body run so that the contact element laterally protrudes beyond the base body. When assembling the The device according to the invention is then required Contact between the contact element and the to contacting body may no longer be in the desired way. In this case the contact element must be detached from the base body and then in the desired mounting position again be attached to this. This rework are time-consuming and therefore costly.

The invention has for its object a Establishment of those mentioned in the preamble of claim 1 Specify the disadvantage of the known Device does not have, that is, an attachment the contact element in the desired mounting position on the base body is relieved.

This object is achieved by the one specified in claim 1 Doctrine solved.

The basic idea of the teaching according to the invention consists in providing adjustment means by means of which the contact element in its position relative to edges of the base body is adjustable. In this way is when attaching the contact element to the Base during the manufacture of the invention Set up a slip and survive of the contact element over the edge of the base body reliably avoided. This simplifies production and saves time and therefore costly Rework.
