Claims

[Scope of utility model registration request]

Permanent magnets with equal magnetic force are placed near both ends of the reed switch, and an imaginary straight line connecting the two magnetic poles of the permanent magnets is perpendicular to the central axis of the reed switch, and both permanent magnets are arranged in the direction of the central axis. In a thermally responsive reed switch, the thermally responsive reed switch is fixedly mounted in a position in which magnetic poles of opposite polarity face each other, and a heat-sensitive ferrite is assembled in an erected manner between opposing magnetic poles of at least one of the two permanent magnets. A reed switch body is configured by being housed in a case made of a magnetic material, and a bar-shaped or plate-shaped ferromagnetic material is installed in a case part of the reed switch body corresponding to both permanent magnets of the thermally responsive reed switch. A thermoresponsive temperature setting mechanism consisting of a thermoresponsive reed switch with a rotatably or slidably mounted adjusting body.
