  • Thermal fuse
    Patent number: 4769902
    Abstract: 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 leaving an air layer, 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.
