Claims

[Scope of utility model registration request]

A temperature switch including a reed switch, a temperature-sensitive magnetic body disposed on the outer periphery of a contact portion of the reed switch, and a pair of permanent magnets disposed on both end faces of the temperature-sensitive magnetic body so as to be attracted to each other. 2. A temperature switch, characterized in that a magnetic body having a Curie point higher than that of the temperature-sensitive magnetic body is disposed so as to cover the outer periphery of at least one of the pair of permanent magnets.
