Abstract
The invention relates to a fusible alloy element (1), in particular for producing a thermal fuse, comprising a fusible element (2), which is made of a material that melts at a trigger temperature, and a support layer (4) on a surface in at least one contacting area of the fusible alloy element (1). According to the invention, the melting temperature of the material of the support layer (4) is greater than the trigger temperature, wherein the material of the support layer (4) is selected such that it dissolves in its solid status in the melted material of the fusible element (2)

20. A method for producing a thermal fuse, the method comprising:
-
placing a contact material on a connection point; placing a fusible alloy element comprising a material that melts at a triggering temperature, and a support layer on a surface at least in one contacting area of the fusible alloy element;
wherein a melting temperature of the material of the support layer is higher than the triggering temperature, and wherein the material of the support layer is selected such that it goes into solution in the melted material of the fusible element in solid state, wherein at least one area of the support layer lies on the contact material; andheating the contact material at least to its melting point, so that the contact material connects with the material of the support layer and the connection point for a period of time, that is limited by the period of time, after which the material of the support layer is completely dissolved in the melted materials of the fusible element and the contact material at the area of the support layer.
