Illustration of the ratchet mechanism of an Enigma machine rotor. Created by en:User:Wapcaplet in Blender with labels and effects in the GIMP.

Stepping motion of the Enigma. All three ratchet pawls (green) push in unison. In the first rotor (1), the ratchet (red) is always engaged, and steps with each keypress. Here, the second rotor (2) is engaged because the notch in the first rotor is aligned with the pawl; it will step with the next keypress. The third rotor (3) is not engaged, because the notch in the second rotor is not aligned; the pawl will simply slide over the curved ring.

Svenska: Framstegningsrörelsen hos Enigma. Alla tre framvridningsknopparna (i grönt) trycker samtidigt. Den första rotorns (1) knopp (röd) är alltid i stegningsläge och flyttar sig vid varje tangenttryckning. Här är den andra rotorns (2) knopp i stegningsläge eftersom kugge och fals är i läge; rotorn kommer att vridas vid nästa tangenttryckning. Den tredje rotorn (3) är inte i framstegningsläge; kuggen kommer bara att glida längs höljet på den skivan.
