description A laminated electric safety fuse which is built up laminated design consisting of various conductive materials which are embedded on an electrically insulating supporting member. The supporting member comprises one or more layers of electrically insulating material, a predominant part of which is a material having good thermal conductivity. In this design a narrowing effect is obtained which is up to 10 times larger than in known fuses, without sacrificing the current-carrying capacity of the non-narrowed parts of the fuse element. The various layers from which the safety fuse is built up can consist of materials with different electric conductivity, providing a new variable for obtaining an increased narrowing effect. The individual layers can be built up as films, e.g. by evaporative deposition.
