  • Electromagnetic switch
    Patent number: 7876185
    Abstract: An electromechanical switch may be actuated in a plurality of modes. A base portion of the electromechanical switch includes first and second electrical ports adapted to be electrically coupled in a plurality of modes. A first electromagnetic coil defines a longitudinal axis and is adapted to receive a first energizing current. A second electromagnetic coil extends along the longitudinal axis in spaced apart relationship with the first electromagnetic coil. The second electromagnetic coil is adapted to receive a second energizing current. The first and second ports are selectively coupled in any one of open-terminated mode, attenuation mode, and a short circuit mode based on the energy state of the first and second electromagnetic coils.
    Type: Grant
