A reed switch apparatus utilizes one or more reed switches to communicate with one or more devices. In one configuration, the reed switch apparatus utilizes a single magnetic field to, simultaneously activate two or more reed switches. In another configuration, two or more reed switches, each acting independent of one another are simultaneously activated by a single magnetic field. Additionally, a method of controlling at least two devices includes exposing a reed switch apparatus to a single magnetic field. Yet another method includes activating a device via the use of a single reed switch mounted to a portion of a warehouse structure. |

A micro-relay module includes a substrate and a lid in spaced apart relation, and a solder ring which bonds the lid to the substrate to define a chamber therebetween. A micromachined relay is integrally formed on the substrate or on the lid within the chamber. A gas is contained in the chamber at a gas pressure which is above atmospheric pressure. Input/output pads are included outside the chamber and electrically connected to the micromachined relay. Large numbers of encapsulated modules may be fabricated on a single substrate by integrally forming an array of relays on a face of a first substrate. A second substrate is placed adjacent the face with a corresponding array of solder rings therebetween, such that a respective solder ring surrounds a respective relay. The solder rings are reflowed in a gas atmosphere which is above atmospheric pressure to thereby form an array of high pressure gas encapsulating chambers. The first and second substrates are then singulated for form a plurality of individual micro-relay modules. |

An electromechanical switch including a non-magnetic cup shaped housing, the interior of which is sealed from the atmosphere with a seal assembly. A first electric terminal extends through the seal assembly and is connected to a coil spring. A second terminal includes a stationary electrode. The electrode extends through the seal assembly and through the coil spring. The coil spring supports a movable contact. A permanent magnet is selectively movable via a solenoid in close proximity to the contact member for selectively moving the contact member in and out of contact with electrode. In the closed position, electric current flows between the first and second terminals and through the coil spring. In another embodiment, an electric magnet provides the necessary flux for selectively moving the contact member. In yet another embodiment, two electrodes extend through the seal assembly and the movable contact is selectively placed in and out of contact with both of the electrodes for selectively controlling electric current flow between the terminals. The coil spring is preferably made of beryllium copper and the movable contact and electrodes are made of molybdenum. The interior of the non-magnetic housing can be evacuated placing it in a vacuum or filled with an arc quenching gas. |

The reeds of a reed switch include convex portions embedded in a glass tube and extending into a cavity defined in the glass tube. The fulcrums about which the reeds are spring-operated are regulated by the positions of the convex portions, rather than by the interface position with the glass tube. As such, a reed switch having desired characteristics can be reliably fabricated regardless of manufacturing process variations. |
