Abstract
A contact element is used for anticipatory earthing of a plug-in module during insertion in guides of a casing or a modular chassis up to plugging in. In order to ensure a reliable and effective protective earthing and a very early conducting away of electrostatic charges during the plugging-in process, a contact element is provided with a clamping area and a holding area. The clamping area is constructed for contact engagement on a circuit board and the holding area is constructed for retaining the contact element on a cross extrusion of the casing or the modular chassis.
