The Harris Worcester Circuit Board consists of a baseboard; terminals; a set of metal connection pillars and a number of clip-on flexible connection strips and accessory units; allowing a variety of circuits to be constructed quickly and easily. Phosphor-bronze connection strips are so designed that when flexed a little they are easily slipped over the pegs where their natural spring holds them in position and ensures a good electrical contact.
