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