ABSTRACT:
A gear-change switch, particularly a stepping switch for controlling gears on bicycles or similar vehicles, has a fixed housing and an actuating element rotatably mounted for rotation in the clockwise and counterclockwise directions to tension or release a traction cable for controlling the bicycle gears. The actuation element comprises a thumb-operated gear-change switch or a twist-grip gear-change switch. The advantage of the switching device lies in the considerable simplification of the design and in the production of the components in plastic material.
