FIELD: personal use articles.
SUBSTANCE: water-heating kettle comprises a switch, which is suited for automatic switching from on position into off position, when water inside the kettle has boiled for some time. The switch is controlled by means of a button element (6), position of which is determined by the switch position. Inside the space (61) of the button element (6) there is a vibration element (20), which comprises a flexible rod (21). When the switch is in on position, the free end (25) of the rod (21) is retained with a drive (10). When the switch is switched into off position, this end (25) of the rod (21) is finally released, as a result the rod (21) starts vibrating, and the button element (6) starts resonating. Thus an acoustic signal is generated.
EFFECT: saving space for elements location due to using kettle components as a resonator or a drive of a vibration element.
