Abstract

The present invention relates to an electrical bridging device comprising two electrical conductors (1, 2) which are electrically isolated from one another and are arranged such that two surface regions of the two conductors (1, 2) are spaced apart from one another by means of a gap. The two surface regions are each covered by a layer (3, 4) which is composed of an electrically conductive material which has a lower melting point than the electrodes. A reactive layer (6) in which an exothermic reaction can be triggered is arranged above the two layers (3, 4). The gap between the two surface regions is selected and the reactive layer (6) is dimensioned and arranged such that the two layers (3, 4) which are composed of the electrically conductive material fuse at the gap owing to the thermal energy which is emitted during the exothermic reaction of the reactive layer (6), and as a result an electrical connection is established between the electrical conductors (1, 2). The proposed bridging device makes it possible, in the triggered state, for high currents to flow through given a low series resistance at the same time, allows permanent, irreversible bridging of the monitored component and can be realized in a cost-effective manner.
