Control device with push button

摘要

The device (4) has a pusher head (14) integrated to a pusher rod (16) that is fixed on a case of a time piece. The rod is axially displaced between a rest position and an active position against a spring (24) for controlling a function of the timepiece. A sealing unit (26) has a cap (28) made of sealing and flexible material e.g. rubber or silicone. The cap covers the pusher head, and is fixed on the case of the time piece. The rod traverses a guiding tube (18) that is fixed in the case and projected from the case.
