Abstract
An electric toothbrush includes a head having a moving portion, a handle, and shaft between the head and the handle. A body portion is hollow and further includes a motor operative to generate motion for driving the moving portion. A battery is located within the hollow section for powering the motor. A first switch, operatively connected to the motor provides momentary operation of the toothbrush. Optionally, a second switch provides for continuous operation of the toothbrush. The first switch can be operated while the toothbrush is in a toothbrush package, such as, for example, a plastic blister pack. A consumer can momentarily observe the operation of the toothbrush before purchasing the toothbrush. The consumer cannot operate the second switch and is thereby prevented from leaving the toothbrush in a battery draining operational mode for extended periods of time.
