摘要： A plunger-operated switch assembly, useful for sensing the presence of a movable object such as a door or window, in which a magnetic reed contact is actuated by a magnet in the form of a disk-like roller plunger, or by a smaller magnet carried in the center of a roller plunger. The roller plunger is located in a cavity defined by a housing and projects through an aperture in a face plate including a flange by which the housing can be mounted recessed in a desired location. The magnetic reed contact is held alongside the cavity containing the roller plunger, so that the housing can be compact. A magnetic electrical conductor lead connected with a magnetic reed is located so as to be effectively within the magnetic field of the actuating magnet when the roller plunger is depressed a small distance so that the magnetic reed switch is actuated by a small movement of the plunger.
摘要翻译：一种柱塞操作的开关组件，其可用于感测诸如门或窗的可移动物体的存在，其中磁簧接触由盘状滚柱柱塞形式的磁体或由较小的磁体携带在滚柱柱塞的中心。滚柱柱塞位于由壳体限定的空腔中，并突出穿过包括凸缘的面板中的孔，通过该凸缘可以将壳体安装成凹陷在期望位置。磁簧接触件被保持在包含滚柱柱塞的腔体的旁边，使得外壳可以紧凑。与磁簧连接的磁导体引线被定位成当滚柱柱塞被压下一小段距离时，有效地位于致动磁体的磁场内，使得磁簧开关由柱塞的小移动致动。

摘要： A magnetically actuated reed switch assembly in which a small permanent helper magnet is attached to a magnetic lead of the reed switch at an end of the reed switch envelope. The lead then may be bent around parallel with a magnetic reed of an encapsulated reed switch. The permanent helper magnet provides an axis of magnetic polarity parallel with the axis of the reed switch, and is magnetized to a level of magnetism which supplies slightly less than enough magnetic flux density to hold the reed switch in a magnetically actuated condition, so that only a small amount of additional flux density needs to be provided. By selecting reed switches within close tolerances and using helper magnets of selected size and strength within close tolerances, satisfactory assemblies may be produced without adjustment of helper magnet position to actuate the switch. The small permanent magnet may alternatively define a bore fitting around the magnetic lead, and may be magnetized after assembly of the magnet and magnetic lead of the switch, thus reducing the amount of time and labor required to manufacture the switch assembly.
摘要翻译：一种磁力驱动的簧片开关组件，其中小的永久性辅助磁体在簧片开关外壳的一端附接到舌簧开关的磁性引线。引线然后可以与封装的簧片开关的磁筘平行弯曲。永久辅助磁体提供与磁簧开关的轴平行的磁极性轴，并被磁化到一定程度的磁性，其供应略小于足够的磁通密度以将簧片开关保持在磁致动状态，使得仅需要提供少量额外的通量密度。通过在紧公差范围内选择簧片开关，并在紧公差内使用所选尺寸和强度的辅助磁体，可以产生令人满意的组件，而无需调整辅助磁铁位置来致动开关。小永磁体可以替代地限定围绕磁性引线配合的孔，并且可以在开关的磁体和磁性引线组装之后被磁化，从而减少制造开关组件所需的时间和人力。
