Claims

[Scope of utility model registration request]

A normally closed temperature switch consisting of a temperature-sensitive magnetic material, a permanent magnet, a reed switch, etc., and a normally open temperature switch consisting of a temperature-sensitive magnetic material, a permanent magnet, a reed switch, and a spacer for a magnetic gap. In a sealed molded temperature switch in which parts are integrally molded with resin, especially for a temperature-sensitive magnetic material, a permanent magnet, and a normally open type temperature switch, the spacer for the magnetic gap is exposed from the resin molded part. A molded temperature switch that is integrally molded with resin.
