  • Patent number: 6133812
    Abstract: A multipole, multiposition switching relay is provided. The switching relay includes an electromagnetic drive coil having a spring-biased plunger slidably mounted therein. 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 magnet located near the drive coil creates a magnetic field which maintains the plunger in the drive coil after the electric current has been disconnected from the drive coil, and the switching relay will remain in the chosen state. 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.
