Abstract
A magnetically controlled switching matrix is composed of magnetic members each having two coils placed thereon and connected into respective row and column energizing circuits, and comprises a generator of decaying alternating current pulses electrically coupled with the row coils, and a direct current generator electrically coupled with columns coils.
Claims7
A magnetically controlled switching matrix, comprising:
- a plurality of magnetic members arranged in rows and columns of said switching matrix, each member made from a magnetic material having at least two stable states of magnetization;
- a first coil of each of said magnetic members placed thereon which induces a magnetic flux in said member and is connected into the electric circuit of said matrix row associated with said magnetic member;
- a second coil of each of said magnetic members placed thereon which induces a magnetic flux in said member and is connected into the electric circuit of said matrix column associated with said magnetic member;
- each said magnetic member magnetically coupled with at least one respective magnetically responsive switch;
- a row selection circuit having an input and an output electrically connected with all of said first coils of said magnetic members;
- a column selection circuit having an input and output electrically connected with all of said second coils of said magnetic members;
- a generator of decaying alternating current pulses with its output connected with the input of said row selection circuit;
- and a direct current generator with the output thereof connected with the input of said column selection circuit.
