The diode matrix as a component in relay switching circuits

THE diode matrix is usually thought of as a component in electronic circuits using diodes of small physical size and having current-carrying capacity in microamperes. This paper describes an application of the diode matrix in a relay switching circuit, where the diodes are small selenium rectifiers with current-carrying capacity sufficient to operate relays. In this application an effort was made to use commercially available selenium-rectifier units for economy in purchasing the small quantity involved.
