ABSTRACT:
For use in low-voltage switchgear there is provided a plug-in contact device for connecting two bars, each of which has two confronting parallel contact surfaces. The contact device includes two co-acting elongated contact fingers which form two electrically parallel-connected current paths between the two bars. At the two end portions of the contact device the current paths intersect each other, whereas in a relatively long middle portion of the contact device the current paths are parallel and lie relatively close to each other, thus obtaining an electrodynamic contact pressure increase.
