Abstract
A switching field for electromechanically switching electrical signal lines with crosspoints. The parts forming the crosspoints comprising membranes, at and between which further parts of the circuit are disposed. The switching field is particularly for communication and data transfer applications. The cross points are disposed matrix-shaped manner and signal lines assigned to the individual crosspoints. The crosspoints are composed of at least two contact surfaces which are movable relative to each other, to the one contact surface, a permanent magnet, and to the other contact surface, a ferromagnetic material with a coil assigned thereto.
Claims19
A switching field for electromechanically switching electrical signal lines with crosspoints, comprising:
- membranes defining the crosspoints;
- and
- circuit means disposed between said membranes wherein said membranes include:
- a mechanically flexible membrane serving as a base;
- a mechanically stable membrane with an opening in an area of said crosspoints, said mechanically stable membrane being applied to said mechanically flexible membrane;
- another flexible membrane applied to said mechanically stable membrane, said another flexible membrane having a lower side to which a permanent magnet is attached and having an upper side to which one of one of two contact surfaces is attached;
- another mechanically stable membrane with an opening in the area of said crosspoints, said another mechanically stable membrane being applied to said another flexible membrane;
- a further mechanically flexible membrane applied to said another mechanically stable membrane, said further mechanically flexible membrane having a lower side with an opposed contact surface of said two contact surfaces attached, and having an upper side to which a ferromagnetic material is provided;
