Abstract: Control button having a metal body (10) provided along its axis with a blind hole (16) closed by a cap (18) and extended by a wall (14) of revolution. The body (10) includes a groove (20) made in the outer surface of the wall (14) and channels (26) connecting said surface to the inside of the blind hole (16). The button further includes a fitting (12) made of synthetic material, formed of a ring (28) closing the groove and extended radially by raised portions (34) as far as the openings of the channels (26) in the wall (14) of a radial structure with several branches (30) closing the channels (26), and a core (32) connecting the branches (30) to secure between them the different parts (28, 30, 32, 34) of the fitting (12).
