ABSTRACT:
Apparatus for representing the connections between a plurality of circuit components to be connected in a circuit and a multiplicity of flow lines in the circuit comprises a first member having a multiplicity of equally spaced lines thereon to represent the flow lines in the circuit. A plurality of connection members are slidably mounted on the first member at spaced positions along the flow lines, each connection member being marked with connection indicia which are spaced apart in a direction perpendicular to the flow lines on the first member by distances equal to the spacing of the flow lines on the first member. The arrangement is such that, in use, the connection indicia and the flow lines can be viewed simultaneously. Sliding movement of the connection members relative to the first member is operable to bring different connection indicia on the connection members into register with flow lines on the first member to indicate which flow lines are required to be connected to components represented by respective connection members.
