Abstract
We discuss the light neutrino exchange mechanisms of the neutrinoless double beta decay in left-right symmetric seesaw models with right-handed gauge boson at TeV scale. It is found that there is a dominance of the conventional light neutrino Majorana neutrino mass mechanism over the momentum-dependent contribution to $0\nu\beta\beta$-decay involving final-state electrons with opposite helicities ($W_L$-$W_R$ exchange, the so called $\lambda$ mechanism).
