ABSTRACT:
A switch device which is disposed between adjacent magnetic bubble domain propagation paths to permit selective, substantially concurrent, exchange of information (i.e. magnetic bubble domains) from one path to the other. The switch is a unique arrangement of substantially conventional components which are selectively activated by application of a current through a control conductor. In one condition, the magnetic bubble domains propagate through the respective paths in the normal manner. In another condition, as a function of the control current supplied to the conductor, the bubbles are exchanged (simultaneously transferred) between the respective paths. In yet another condition, the bubbles in one path are replicated and supplied to another path.
