Claims

[Scope of utility model registration request]

A temperature switch configured by fixing a temperature-sensitive magnetic material and a permanent magnet to the outer periphery of a reed switch is fixed with thermoplastic resin or thermosetting resin, or is molded in a case. A temperature switch characterized in that at least a part of the temperature-sensitive magnetic body of the magnetic body and the permanent magnet is exposed, and the exposed surface is in direct contact with a surface to be measured or an atmosphere.
