を有する圧力スイッチを提供することである。DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a pressure switch having a structure that actively utilizes the properties of mercury, such as fluidity, conductivity, surface tension, and diaphragm flexibility.
以下に図によって詳細に本発明を説明する。The invention will be explained in detail below with reference to the figures.
第１図と第３図は本発明の正面断面図を示し、第１図は
スイッチがＯＦＦの状態、第２図はＯＮの状態である。1 and 3 show front sectional views of the present invention, FIG. 1 shows the switch in the OFF state, and FIG. 2 shows the switch in the ON state.
第２図は第１図の上面図を示す。FIG. 2 shows a top view of FIG.
非電導性である上側ダイアフラム２と下側ダイアフラム

い合せて突起２ａ、３ａを設ける仁とによシ空間１１を
形成し、空間１１に適量の水銀１が封入されている。A non-conductive upper diaphragm 2 and a lower diaphragm 3 are overlapped, and a space 11 is formed by placing protrusions 2a and 3a facing each other in the center of the diaphragm 2.3. 1 of mercury is enclosed.
空間１１の外周にはリード線４６を結合された接点へか

フラム２と下側ダイアフラム３を押さえ、ポルト１２．
ナツト１３、又は接着剤等にて結合されている。At least two lead wires 46 are arranged on the outer periphery of the space 11 to the connected contacts, and hold the upper 5 diaphragm 2 and the lower diaphragm 3 in the upper case 5 and lower case 6 forming the diaphragm chamber. 12.
They are connected using a nut 13 or an adhesive.
上側ケース５にはダイアク２ム室内に圧力を導入する上
ｎニツプルフとダイアフラム２の作動量を鯛整する上側
スゲリング９が設置され、下側ケース６にも同様に下側
ニップ、ル８と下側スプリング１０が設置されている。The upper case 5 is equipped with an upper nip valve that introduces pressure into the diaphragm 2 chamber, and an upper nip ring 9 that adjusts the operating amount of the diaphragm 2, and the lower case 6 is also equipped with a lower nip, a lower nip 8, and a lower nip ring 9 that adjusts the operating amount of the diaphragm 2. A side spring 10 is installed.
本発明の圧力スイッチはほぼ水平状態で使用されるもの
で、ダイアフラム室に圧力が作用していない状態は第１
図に示す如くであシ、上側スプリング９が上側ダイアフ
ラム２を押し下げており、上側ダイアフラム２と下側ダ
イアクラム３は中央部が下方に凹んでいる。The pressure switch of the present invention is used in a substantially horizontal state, and the state where no pressure is acting on the diaphragm chamber is in the first position.
As shown in the figure, the upper spring 9 presses down the upper diaphragm 2, and the upper diaphragm 2 and the lower diaphragm 3 are recessed downward at their central portions.
従ってこの中に封入されている水銀ｌは中央部に位置し
、接点４に接触せずＫＯＦ’Ｆ’状態を保持している。Therefore, the mercury l sealed therein is located in the center and does not contact the contact point 4, maintaining the KOF'F' state.
今第３図に示す如く下側ニップル８よシ圧力Ｐｌを作用

ダイアフラム３と上側ダイアフラム２の中央部が上方に
張り出している状態では水銀１はダイアフラム間の外周
Ｋ（ｋ、動し、接点４と接触しＯＮ状態となる。Now, as shown in FIG. 3, when pressure Pl is applied through the lower nipple 8, the center portion of the lower diaphragm 3 bends upward, and the lower diaphragm 3 is in contact with the central protrusion 3aK of the lower diaphragm 3. 2 will also transform together. In this state that the center portions of the lower diaphragm 3 and the upper diaphragm 2 are projecting upward, the mercury 1 moves around the outer circumference K (k) between the diaphragms, contacts the contact 4, and becomes in the ON state.
１！に、下側ニップル８よシ圧力ＰＬが作用している第
３図の状態ＫＰ１よシ高い圧力を上側ニップル７に加え
ると第１図の状態に戻りＯＦ’Ｆ’状態となる。1! If a higher pressure is applied to the upper nipple 7 than the state KP1 shown in FIG. 3 in which the pressure PL is acting on the lower nipple 8, the state returns to the state shown in FIG. 1 and becomes the OF'F' state.

状態が得られ、応用範囲は沢山あると考えられる。In this way, the present invention is a pressure switch that actively utilizes the characteristics of mercury, which is electrically conductive, fluid, and has a large surface tension, and the flexibility of a diaphragm. It has a two-way structure, so when one pressure is applied and the other pressure is applied, orr
It is believed that there are many possible applications.

しくは離脱を利用した圧力スイッチ。A certain space is provided outside the 7 flange of the two stacked non-conductive diaphragms, and the space is sealed with mercury, and a lead wire with at least two or more contacts is inserted inside the 7 flange. The diaphragm is installed so that the contact point is located nearby, and the two diaphragms are pressed up and down with a case with 7 flanges connected to the pressure intake nipple, so that the pressure applied to the diaphragm and the pressure direction are determined. A pressure switch that deforms up and down and utilizes the feeling of the flowing mercury contacting or separating from the contact points.
