２と永久磁石（図示せず）との距離は小さくしなければ
ならない。Originally, the water level in the water tank 1 was detected by the reed switch 2 using the magnetic force of a permanent magnet (not shown) linked to a float (not shown).
In order to operate the reed switch 2, a small permanent magnet (not shown) must be used, and the distance between the reed switch 2 and the permanent magnet (not shown) must necessarily be small.
従って、第１図に示したように従来の実施例では、成る

、リードスイッチ２を交換する時には、取付板５を水槽
１から取り外さなければならなかった。However, with this mounting method, the glass enclosure part 3 is likely to malfunction because the lead part 4 is bent, and the mounting plate 5 must be removed from the aquarium 1 when replacing the reed switch 2. Ta.
本考案はこのような欠点を除去したものであり、本考案
−実施例を第２図に基き説明する。The present invention eliminates these drawbacks, and an embodiment of the present invention will be described with reference to FIG.
尚、第１図と同一部分を示すものについては同一図番を
使用するものとする。Note that the same figure numbers will be used for parts that are the same as those in FIG. 1.
取付板５の中央部に細長の透孔１１を設け、透孔１１の
両端にリードスイッチ２のリード部４の銅箔等の取付部
１２．１２を設ける。An elongated through hole 11 is provided in the center of the mounting plate 5, and mounting portions 12, 12, such as copper foil, for the lead portion 4 of the reed switch 2 are provided at both ends of the through hole 11.
リードスイッチ２のガラス封入部３を透孔１１に嵌め込
み、リード部４を銅箔等の取付部１２゜１２にハンダ付
けをすることにより取付板５とリードスイッチとは一体
となる。The mounting plate 5 and the reed switch are integrated by fitting the glass enclosure part 3 of the reed switch 2 into the through hole 11 and soldering the lead part 4 to the mounting part 12 12 made of copper foil or the like.
更に、これらの一体となったものを水槽１底部の突起９

先端を溶融して取付板５を水槽１に取り付ける。Furthermore, these integrated parts are attached to the protrusion 9 on the bottom of the aquarium 1.
, 9 are inserted into the holes 10 and 10 of the mounting plate 5, and the tips of the protrusions 9, 9 protruding from the mounting plate 5 are melted to attach the mounting plate 5 to the aquarium 1. .
尚、８，８は取付板５の取付部１２．１２を介してリー
ドスイッチ２のリード部４に取り付けられたリード線で
ある。Note that 8 and 8 are lead wires attached to the lead portion 4 of the reed switch 2 via the attachment portions 12 and 12 of the attachment plate 5.
以上の如く、本考案による水位検出装置に於いては、リ
