The invention relates to an electric motor-operated on-load tap changer (1) comprising an emergency drive. An electric motor (3) and a power store (13) of said on-load tap changer (1) are mechanically coupled by means of a gear (5) that is provided with a gear housing (90). The gear (5) comprises a gear shaft (61) on which a toothing (55) is designed. For manual emergency operation, the claimed gear shaft (61) has an extension (62) which comprises a free end (65) for attaching a tool (95).
