Abstract: A flat, flexible cable construction comprises two flat, flexible insulating strips each including a plurality of electrical conductors extending along one side of one strip and the opposite side of the other strip, which electrical conductors are exposed at their ends on the inner contacting faces of the two insulating strips. Each of the insulating strips is formed with a transversely-extending slit starting from the edge of the side not including its respective electrical conductors and terminating short of the side including its respective electrical conductors, whereby the two ends of the insulating strips may be transposed by inserting the non-slitted side of one into the slitted side of the other to thereby transpose the outer exposed ends of the electrical conductors from the inner contacting faces of the insulating strips to the outer non-contacting faces of the insulating strips for connection to an electrical connector.
