Variants of a one-boson-exchange potential are applied to elastic nucleon-deuteron and electron-deuteron scattering. The models differ with respect to the treatment of the pion-nucleon vertex, where either a small coupling constant or a soft form factor is employed. We find that these variations do not affect [ital Nd] observables, but that they have a sizable effect on [ital ed] quantities via exchange currents of the pion. Taking into account also exchange currents of the [pi][prime] reduces the effect to a large extent.
