The individual gear stages are formed in the switch through one or more controllable pawls (8,9,10) which produce a trigger switch so that several gear stages can be switched through by a single switch movement in the tension direction (6) and in the release direction (7). The switch has a control element (2a) which can be operated both in the tension direction and release direction to change gear and returns to its starting position when the switch process is completed. |
