Abstract

The invention is about a sliding mechanism for a portable electronic device. Among others, the sliding mechanism comprises a first part with a guiding groove where the first part is arranged along a longitudinal axis. The sliding mechanism also comprises a second part which is movable along the longitudinal axis in relation to the first part. Additionally, the second part comprises a protrusion which is movable in the guiding groove. Moreover, the sliding mechanism further comprises an element which is used for transferring torque to one of the parts of the sliding mechanism, such that the protrusion is held in at least two stable positions in the guiding groove.
