Abstract
The mode selection system for a power toothbrush includes a first switch (25) operable to control the ON/OFF condition of the toothbrush and a second switch (29) operable when the first switch is in the OFF condition to select one of a plurality of possible modes of operation programmed in the toothbrush. A pre-established time is set during which the ON/OFF switch must be operated to an ON condition after the mode selection switch has been operated to select a particular mode. The selected mode is indicated by a lit LED on a handle portion of the toothbrush.
