We establish constraints on a general four-fermion contact interaction from
precise measurements of electroweak parameters. We compute the one-loop
contribution for the leptonic $Z$ width, anomalous magnetic, weak-magnetic,
electric and weak dipole moments of leptons in order to extract bounds on the
energy scale of these effective interactions.
