Abstract

An electric toothbrush is disclosed. The electric toothbrush includes at least one switch element and a control unit. The at least one switch element is operable by a user to switch the toothbrush to an on/off state, and operable by a user during the time that the at least one switch element is in its on state to select a brushing mode from a set of at least a first brushing mode and a second brushing mode. The control unit is arranged to control the electric toothbrush such that when the at least one switch element is operated to select a particular brushing mode in the on state, the toothbrush will then operate in that particular selected brushing mode when the at least one switch element is thereafter switched to an off state and then subsequently switched back to an on state, provided that the toothbrush was in the off state for a time period less than a threshold period (T).
