Having Motor-driven Switch Patents (Class 379/305)
  • Patent number: 6510222
    Abstract: A line multiplier is formed of n upstream lines and m downstream lines where m>n by providing a micro-technology array of m×n crosspoints switches using, e.g., magnetic latching, wherein the latching magnets are heated to the Curie temperature to cause the state of a switch to change.

  • Patent number: 5952739
    Abstract: Multiple pairs of stationary and moveable contacts are toggled simultaneously between an open and closed position to disconnect or connect a meter from or to a line power source, by a reciprocating operator driven by low power clock motor. The operator is connected to the contacts through a series of pivotally coupled toggle links that are spring biased to maintain the contacts in either of two stable states, open or closed. The disconnect switch is housed as a modular unit that is interposed between the meter socket and the meter. The switch is remotely actuated and cycles the motor through a pre-determined number of degrees of rotation sufficient to change the state of the contacts.
