ABSTRACT:
A selective switching circuit which is operative to successively switch a plurality of other circuits, one at a time in a predetermined order, into an existing circuit configuration. An embodiment of the invention is described in relation to a magnetic strip card writing device, whereby information to be written on each of a plurality of strips is successively stored in corresponding registers, and later applied to the strips all at one time. Information in any of the registers may be preserved therein, with new information to be recorded being directed into the next ordered register.
