  • Publication number: 20100012646
    Abstract: A hot water kettle has an on/off switch, which is adapted to automatically switch from a closed position to an opened position when water which is present inside the kettle has been boiling for a while. The on/off switch is operable through a button element (6), a position of which is determined by the position of the switch. Inside a space (61) of the button element (6), a vibratory member (20) comprising a flexible bar (21) is arranged. When the on/off switch is in the closed position, a free end (25) of the bar (21) is retained by an actuator (10). As soon as the on/off switch switches to the opened position, this end (25) of the bar (21) is eventually released, as a result of which the bar (21) starts to vibrate and the button element (6) starts to resonate. In this way, an acoustic signal is generated.
