部材（鎖線で示す）により被覆される。 A cylindrical body 5 made of a resin-molded glass tube portion of a reed switch with a flange 51 provided at one end is assembled in the order shown in the exploded perspective view of FIG. 3 to construct a temperature switch. That is, the non-magnetic annular body 6 is fitted onto the outer periphery of the cylindrical portion 52 of the cylindrical body 5 , and then the permanent magnet 1, the temperature-sensitive magnetic body 2, and the permanent magnet 1' are attached to the first
Fit in the same direction and order as shown in the figure, and then fit the non-magnetic annular body 6' and insert the lead wire of the reed switch on the opposite side of the flange 51 into the small hole provided in the center of the holding plate 7. through the flange 5
The annular assembly consisting of the magnets 1, 1', the temperature-sensitive magnetic material 2, and the non-magnetic annular bodies 6, 6' is held between the holding plate 7 and the holding plate 7, and the holding plate 7 and the lead are joined together by soldering. . The length of the annular body 6 on the flange 51 side is selected so that the temperature-sensitive magnetic body 2 faces the contact part of the reed switch 4, and the length of the annular body 6' is such that its upper end face is closer to the end face of the cylindrical part 52. Select so that it protrudes slightly. After confirming the operating characteristics of the temperature switch, the outer surface is covered with an insulating member (shown by a chain line) such as a heat-shrinkable tube or powder coating while leaving the leads exposed.
