Abstract
A switch for actuating a gear on a bicycle includes a housing with an inner toothing formation, a grip part and a rotary part with a cable drum for a fraction cable. The grip part having an integrally formed section for actuating an elastic element on the rotary part so that when the grip part is rotated in a switching direction which releases the traction cable the elastic element is pretensioned until a disengagement member on the grip part disengages a pawl on the rotary part which interacts with the inner tooting formation in the housing. Both the pawl and the elastic element are connected integrally to the rotary part resulting in advantage in terms of the production and assembly of the switch.

A switch for actuating a gear on a bicycle, comprising:
- a housing having an inner tooth formation;
- a rotary part and a cable drum on which a traction cable is mountable;
- a grip part;
- a pawl arranged for engaging said inner toothing formation;
- a disengagement means for selectively disengaging said pawl from said inner toothing formation;
- and
- at least one elastic element arranged between said rotary part and said grip part, a first one of said grip part and said rotary part including said at least one elastic element and a second one of said grip part and said rotary part including an integrally formed section having a contour that presses against said at least one elastic element producing a pretension during rotation of said grip part relative to said rotary part in a traction cable release direction prior to disengagement of said pawl by said disengagement means.
