  • Patent number: 8847715
    Abstract: A permanent magnet is pivotally mounted in a top spacer layer of a switching device and rests on a flex arm created in an underlying flex circuit layer. The underside of the flex arm rests on a thin bar formed in a lower spacer layer beneath which lies a base layer including an electromagnet. Activation of the electromagnet causes rotation of the flex arm to thereby close and open electrical contacts formed respectively on the underside of the flex arm and on the top surface of the base layer.

  • Patent number: 7633361
    Abstract: An improved electromechanical RF switch provides enhanced reliability and lifespan by incorporating a middle plate between the case and base elements for locating the guide pins, reed holders and reeds to increase accuracy in critical component alignment. The middle plate reduces required precision during assembly of the switch, thus increasing assembly accuracy while reducing labor cost. The guide pins are made of a hard insulator such as glass to generate less wear particles, and the reed holder has a groove filled with lubricant to trap any wear particles that result from sliding friction during switch operation. Optionally, a low-friction bushing is used within the case bore to further reduce sliding friction during reed holder travel. The reeds are made of thin, flexible metal and have ends shaped so that when the ends contact switching terminals, a wiping action removes any surface contamination from both the reed ends and the terminals.

The plunger is operably connected to a switching apparatus for connecting and disconnecting terminals of coaxial connectors. The drive coil pulls the plunger into its hollow center when an electric current is applied to the drive coil.

A second drive coil may be provided which shunts, or reverses, the magnetic field, allowing the plunger to return to its original position due to the biasing force provided by the spring. Energizing the second drive coil automatically resets any previously selected position of the first drive coil to its original position.

  • Patent number: 4766401
    Abstract: A switching network for coaxial transmission lines switches both the center conductors and the shields to allow floating measurements and eliminate the effects of ground loops. The shields are switched even though the coaxial relays used to switch the center conductors do not themselves also switch the shields. This is accomplished by using two coaxial relays having connected center conductors, each of which coaxial relay is itself shielded, and a third relay to selectively connect and disconnect the shields of the coaxial relays. All three relays open and close in unison. Although this arrangement provides excellent isolation when open within the circuit where it is used, there is unfortunately a coupling mechanism between pairs of such circuits having such relay arrangements that are closed. This coupling mechanism produces crosstalk between such pairs of circuits. The crosstalk current tends to flow in a resonant circuit.

  • Patent number: 4496919
    Abstract: A relay for switching of ultra high frequency circuits has three spaced-apart coaxial type contacts including a central or common contact. Two contact blades are disposed in opposed relation to the coaxial contact for alternate movement from a first position in which one rigid contact engages the central coaxial contact and one side contact while the other rigid contact is grounded, and a second position in which the other rigid contact engages the central contact and another coaxial contact and the first rigid contact is grounded. Pusher elements connected to the respective rigid contacts are connected to opposite sides of a leaf spring supported at its center. A pivotal armature alternately presses on one end or the other of a leaf spring to drive one rigid contact against its two coaxial contacts and to permit the other end of the leaf spring to pull the other rigid contact into engagement with the ground plane.

  • Patent number: 4330766
    Abstract: An electromechanical T-switch is achieved by connecting a bistable reed switch between each of the four ports of the T-switch to form a coaxial transmission line between ports. Each electromechanical reed switch is realized by a pair of contacts constituting the input and output ports of the switch, a reed conductor bridging the gap between the two contacts, a first permanent magnet for holding the reed conductor against the contacts, a second permanent magnet for holding the reed conductor away from the contacts, and electromagnetic coils around each of the first and second permanent magnets for changing the state of the switch.

  • Patent number: 4298847
    Abstract: A multiposition microwave switch with a cavity comprising a center and a plurality of radial portions with acutely extended legs. The central coaxial connector selectively communicates with one of a plurality of peripheral connectors, the others being terminated by impedance matching resistors housed in the legs and isolated and shielded from the central connector. The cavity is housed beneath a plurality of pivotal rockers responsive to magnetic actuating means. First and second conductive reeds are spring loaded in the radial portions and legs, respectively, of the cavity and are mechanically responsive to the rockers such that when a first reed is conducting between central and peripheral connectors, its complimentary second reed is shorted to the housing. When the first reed is shorted to the housing, its complimentary second reed terminates the peripheral connector by conducting between it and the resistor.

  • Patent number: 4162469
    Abstract: A magnetically-locked switch assembly includes a switch unit having internal contact means positioned by an actuator arm between open and closed positions. Unauthorized actuation of the actuator arm is prevented by a locking pin which is displaced to release the actuator arm only in the presence of an externally applied magnetic field. The actuator arm is mechanically actuated from outside the switch housing through a slip-clutch to prevent damage to the actuator arm by application of excessive force when the actuator arm is locked.

  • Patent number: 4044320
    Abstract: A coaxial 1-of-n relay transfer switch has reed switches arranged in electrically conductive, non-magnetic tubes. The reed switches are arranged in a star configuration in such a way that one terminal of each reed switch is connected to a branching point within a metallic head enclosing the branching point, and are connected to the inner conductor of a coaxial input line at the metallic head. The other end of each reed switch is connected to a coaxial output line. The metallic head and the metallic tubes which enclose the reed switches are constructed, with respect to their interiors, that, viewed electrically, they add inductances between the inner conductor of the coaxial input line and the branching point, on the one hand, and, on the other hand, between the branching point and the reed switches.

  • Patent number: 4044319
    Abstract: A coaxial 2-of-n relay transfer switch has reed contacts arranged in electrically conductive, non-magnetic tubes. The reed contacts (reed switches) are arranged in two groups of n reed switches in each group in a star configuration with the reed switches of each group forming the edges of a pyramid. One end of each reed switch of a group is connected to the like end of the other reed switches of that group to form a first branching point to a respective coaxial input line. The other end of each reed switch is connected to a like end of a reed switch in the other group to form a respective second branching point to a respective coaxial output line.

  • Patent number: 3993970
    Abstract: A coaxial cable switch comprising a plurality of sealed reed, magnetically responsive switches serially connected in alternating directions which switches act as the inner signal path of a coaxial conductor. The outer coaxial conductor consists of a copper "corrugated" sheet within the adjacent and oppositely facing channels of which the individual switches are respectively positioned. The open sides of the channels are covered with metallic tape by means of a conductive adhesive and a single winding encircles the structure for the simultaneous operation of the reed springs.
