ABSTRACT:
A matrix arrangement is disclosed of bistable, magnetically latched reed relays. Each matrix multiple includes a selection unit comprising a generator for transmitting successive pulses of opposite polarity which switch the relays on that multiple to a first stable condition. The relay coils are arranged so that superimposing the pulses of two multiple selector units switches the corresponding relay or relays to the second stable state.
