Horological switchable display mechanism

A horological mechanism, comprising:

• a first mechanism comprising a first output wheel set capable of pivoting;
• a second mechanism comprising a second output wheel set capable of pivoting, the position of said first output wheel set being associated with a first input variable, and the position of said second output wheel set being associated with a second input variable, whereby said first mechanism and said second mechanism are arranged to control, each in turn, the motion of a third mechanism, and the driving of at least a third output wheel set comprised in said third mechanism;
• a switching and coupling mechanism arranged for coupling between said first mechanism or said second mechanism, which constitute two inputs each operating continuously, and said third mechanism constituting an output;
• and
• control means operable by a user to uncouple the mechanism from among said first mechanism and second mechanism that is engaged with said third mechanism, and to engage the other from among said first mechanism and second mechanism with said third mechanism,
• wherein said switching and coupling mechanism couples, in a single angular position per revolution said first mechanism or said second mechanism, and said third mechanism, said switching and coupling mechanism allowing for coupling solely in said single angular position, and
• wherein said switching and coupling mechanism comprises a structure, which comprises a raised edge, with which a strip comprised in said control means cooperates via an abutment in order to modify the position of a sliding wheel set comprised in said switching and coupling mechanism.
