摘要： Pressure switch is shown which is accommodated in a pressure vessel (1) filled with a gas at a first pressure (P1), such as for a safety air bag in a road vehicle. The device comprises a pressure container (12) filled with a gas at a second pressure (P2), which container has at one side a flexible diaphragm (18) which reacts to the difference in the two pressures and interacts with an electrical circuit. The container is fitted with one side adjacent to and opposite a wall portion (14, 106, 214, 238, 256) of the pressure vessel and a magnetic element (16, 26, 240, 246/248) is operatively coupled to the diaphragm. The wall portion of the pressure vessel is made of non-magnetic material, and near the other side of the wall portion a magnetic field sensitive switching element (40) is mounted opposite the diaphragm magnetic element. A window element (13) of magnetic material may be placed in the wall portion of non-magnetic material, in line with the magnetic element and the switching element. An armature (232, 254) extending through the wall portion may be used to concentrate the magnetic flux path. The armature can be arranged to function in a head-on mode (232) or on a slide by mode (254). The magnetic curve of the system can be adjusted by using a bias magnet (216). A two part assembly permits attachment of the switch to the vessel without problems associated with the heat of welding from adversely affecting associated electronics and a circuit (222) is shown for providing a two wire output having voltage levels indicative of selected conditions.
摘要翻译：示出了压力开关，其被容纳在充满第一压力（P1）的气体的压力容器（1）中，例如用于公路车辆中的安全气囊。该装置包括填充有处于第二压力（P2）的气体的压力容器（12），该容器在一侧具有柔性隔膜（18），该隔膜对两个压力的差异起反应并与电路相互作用。该容器的一侧与压力容器的壁部分（14,106,214,238,256）相邻并与之相对，并且磁性元件（16,26,240,246/248）可操作地连接到隔膜。压力容器的壁部分由非磁性材料制成，并且在壁部分的另一侧附近，磁场敏感开关元件（40）与隔膜磁性元件相对地安装。磁性材料的窗元件（13）可以放置在与磁性元件和开关元件对齐的非磁性材料的壁部分中。延伸穿过壁部分的电枢（232,254）可用于集中磁通量路径。衔铁可以布置成在迎头模式（232）或模式（254）下的滑块中起作用。系统的磁性曲线可以通过使用偏置磁体（216）进行调整。两部分组件允许将开关附接到容器而没有与焊接热有关的问题对相关电子元件产生不利影响，并且示出了用于提供具有指示选定状态的电压电平的双线输出的电路（222）。

摘要： An inner space of an outer case (20) is partitioned by a gas permiable diaphragm into a fluid pressure operating chamber (22b) and a reference pressure operating chamber (26a). The former chamber communicates with a pressurized fluid inlet hole (22a) formed in the case, and the latter communicates with a pressure equalizing hole (54) formed in the case. Electrical contacts (50, 52) are stored in the latter chamber to perform on/off-operation in response to deflection of the diaphragm caused by pressure change of pressurized fluid in the former chamber. Outer connection terminals (46) for the contacts are supported by the outer case. A filter (60) is provided in the equalizing hole.

摘要： Die Schaltvorrichtung (26) des Druckschalters (10) weist ein feststehendes (30) und ein mit einer Schnappfeder (50) gekoppeltes bewegliches Kontaktelement (32) auf. Diese einen Schaltkontakt bildenden Kontaktelemente (30, 32) sind zwischen einer gehäuseseitigen Einspannstelle (62) und einem Betätigungspunkt (44) angeordnet, an welchem eine Membran (24) mittels eines Stössels (46) an einer den Schaltkontakt betätigenden Blattfeder (34) angreift. Dabei befindet sich der Betätigungspunkt (44) an einem längeren Hebelarm als der Schaltkontakt. Dies bewirkt eine Kraftübersetzung vom Membranhub auf den Schaltkontakt und gewährleistet durch die Verstärkung des Kontaktdruckes eine erhöhte elektrische Schaltsicherheit.

摘要： A normally open pressure responsive switch having upper and lower housings with a snap acting member and an electrically conductive member sandwiched therebetween. The housings each include a body with a hollow center portion and the lower housing has a contact in the center portion extending externally of the member. The snap acting member is in constant engagement with the sandwiched conductive member and normally out of engagement with the contact. When pressure is applied which is sufficient to cause the snap acting member to snap connection is made with the electrically conductive member in the lower assembly. An elastomeric sealing member is mounted in the upper housing and has a neck portion received in the hollow center portion, an integrally attached flange biased against the electrically conductive member and lower housing and an integrally attached lobe extending above the upper housing to seal off the hollow center portion when the switch is mounted at a switch receiving seat.

摘要： A pressure receiving member which has a diaphragm held in a pressure receiving case is manufactured independently of a main sensor body member, which has a switch accommodated in a switch case. The pressure receiving member and the main sensor body member are then assembled to provide a pressure sensor. According to the present invention, since the pressure receiving portion and the main sensor body are manufactured individually, a diaphragm inversion movement test can be carried out individually of the testing of switch turning on and off, and hence only satisfactory pressure receiving portion and main sensor body which passed the respective tests will be utilized in the operation fo assembling pressure sensors.
