(57) A button-cover (1) including a little spring (5) for engagement to the button (10),
which little spring (5) is substantially flat and has two appendixes (7), for articulation
to the button-cover (1), an elastic tongue (9) partially bent in order to guarantee
the stability of the two positions of elastic equilibrium and at least an appendix
(11), diametrically opposed to the articulation appendixes (7), which leans on the
edge of the button-cover (1) and possibly projects therefrom for a limited amount
to make easy the hold of little spring (5) and the rotation thereof with respect to
the button-cover (1).
