〔産業上の利用分野〕
本考案は、リードスイツチと永久磁石を組み合
せてなる磁気スイツチに関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magnetic switch that combines a reed switch and a permanent magnet.

Conventionally, in this type of magnetic switch, as shown in Fig. 3, a reed switch always closes the contact point by a permanent magnet 2 fixed to its outer periphery. When the permanent magnets 6a and 6b, which have different magnetic properties, approach each other, the contact point is opened.

つたり、引つ張つたりすると、封着部が破損し、
安定な動作が得られなくなる恐れがある。 The reed switch used in this type of magnetic switch is particularly susceptible to glass breakage, and if the lead is twisted or pulled, the sealed part will be damaged.
There is a possibility that stable operation may not be obtained.

The reed switch 1 and the magnet 2 were positioned using the reed switch 1 and the magnet 2, and were bonded together using the resin 3.

う欠点があつた。 However, it is not perfect in terms of preventing external forces from being applied to the leads, and if external forces such as twisting, pulling, or bending are applied to the leads during the assembly process, there is a risk that the sealed portion of the reed switch will be damaged. Moreover, since there are a large number of parts, there is a drawback that it requires a lot of man-hours.
本考案はこのような欠点を除去し、構造、組立

It is an object of the present invention to eliminate such drawbacks, provide a magnetic switch that is simple in structure and assembly, and prevents cracking and damage not only to the glass portion of the reed switch but also to the reed sealing portion.

In the present invention, a magnetic switch is constructed by fixing a permanent magnet to the outer periphery of the reed switch, and is integrally molded with thermoplastic resin or thermosetting resin, leaving the lead wire of the reed piece.

Even if an external force is applied to the lead wire, it will not be transmitted to the inside, so there is no risk of damaging the glass part of the reed switch.

FIG. 1 shows an embodiment of the present invention. In the figure, a switch 1 enclosed in a glass tube and an annular permanent magnet 2 are integrally molded with a thermoplastic or thermosetting resin 5, except for the lead wire of the reed switch.

With this structure, the only assembly parts are the reed switch and the annular permanent magnet, so the structure is simple and the assembly work is easy. Furthermore, since the glass portion of the reed switch, the permanent magnet, and a portion of the reed piece are completely covered with the molding material, no external force is applied to the glass portion of the reed switch. As a result, stable operation can be achieved without damage to the glass portion.

の磁気スイツチを提供することができる。 As mentioned above, the present invention has an integrally molded structure in which the glass part of the reed switch and the permanent magnet around its outer periphery are completely molded with molding material.
It is possible to provide a highly reliable, low-cost magnetic switch that is easy to assemble, is extremely resistant to external forces applied to the lead piece, has stable operating characteristics, and has stable operating characteristics.
