<p>A thermal cut-off fuse of a self-restoring type, which breaks the electric continuity between a pair of lead wires in response to melting and voluminal expansion of a temperature-sensitive member upon rise of the ambient temperature to a prescribed temperature and, in response to restoration of spring means upon fall of the ambient temperature below the prescribed temperature, re-establishes the electric continuity between the pair of lead wires.</p> |
