Electric toothbrushes are designed to make the brush head and bristles move in rapid motions, either in a back-and-forth motion, or in a back and forth motion that also rotates both clockwise and anti-clockwise. Electric Tooth brushes also need to be protected from the environment by sealing the functioning electronics and motor inside the housing.
The basic design of an electric toothbrush is that the whole working assembly is sealed. Most of the controls for operating the electric toothbrush and turning it on or off require sealed switches that will not be affected by water. This is where Reed Sensors are used.
The switches and buttons that are encased in the the rubber body use magnets that trigger the reed switches inside that require multiple presses to change speed and a single short press or a long press of the power button to turn the electric toothbrush on and off. This is achieved by mounting tiny magnets under these buttons that activate or signal cycle the reed sensors mounted inside the toothbrush assembly. This way the external rubber mounted magnets activate the circuits inside the Electric Toothbrush.
