The charge-independence breaking of the nuclear interaction is analyzed by means of energy differences \namong analog states in T=1 isobaric multiplets. Data on triplet energy differences in the sd, pf, and pf5/2g shells, i.e., 18<A<66, are reproduced with very good accuracy by large-scale shell-model calculations taking \ninto account, aside from the Coulomb interaction, a single isotensor schematic interaction of monopole-pairing \ntype. It is shown that the effect on the triplet energy differences of this isospin-breaking interaction is of the \nsame magnitude as the Coulomb one. Moreover, its strength is the same for every single-particle orbital of the \nconsidered model space.
