THERMAL FUSE Abstract of the Disclosure A thermal fuse is formed by a conductive path formed in a ceramic body, the path being of a fusible alloy. A ceramic substrate and a ceramic cover, both in green form, are fused together with defined channels. The channels can be defined by a material which is burnt out, preferably when the ceramic members are fused together. The channels can be defined in other ways. The channels are filled with a fusible alloy, end contacts being provided. Several channels can be formed in one assembly. The assembly can then be cut into separate fuses, each with one channel.
