Abstract
A switching unit is used to connect transmission lines by means of a matrix of relays. The relays used are magnetic reed relays. These are made of two contacts on magnetic material strip in a glass bulb. The unit has a relay at each coordinate of the matrix. Each relay has two pairs of coils, Each pair of coils can be supplied by a pulse of high intensity for a set duration. One set of coils receives a pulse of shorter duration than the other set. The coils of one set are separated from the coils of the other set by a magnetic shield. The position of the elements of each relay is not important.
