1. A dose setting mechanism comprising:
a dose knob;
a dose selector;
a radial projecting rib positioned circumferentially on an inside surface of the dose selector; and
a snap element comprising a protrusion,
the radial projecting rib extending along a circumference of the inside surface of the dose selector such that a longitudinal axis of the radial projecting rib deviates from a longitudinal axis of the dose selector, and
the radial projecting rib having a reduced section or a cut-out that allows the radial rib to move axially relative to the protrusion to initiate dose delivery.
