Push button assembly particularly for a watchcase

摘要

The watch case (1) is of plastic material and provided with a hole (3) in which a push button (6) may slide. The end (12) of the stem (7) of the push button includes a bulge (13) the diameter of which is greater than that of the neck (11) formed at the end of the hole opening into the interior of the case (1). When the stem (7) is introduced into the hole (3) of the wall (2) the bulge (13) elastically deforms the neck (11) which afterwards reassumes its initial form and assures axial positioning of the stem (7).
