Reed sensors in Electric Toothbrushes

Reed switches in electric toothbrush
Electric Toothbrush

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.

The basic design of an electric toothbrush is that the whole working assembly is sealed within a water proof body with an O-ring sealed battery compartment which protects the battery from moisture. 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 ultra-miniature reed switches help. 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 switches mounted inside the toothbrush assembly.

Recommended Products

The Reed Switches and Reed Sensors used in such applications need to be robust, durable and efficient in meeting a high life expectancy. Our engineers work hard in life testing our products under various conditions, and we want to ensure that the the end product has a long working life. Although we wouldn’t want to restrict our products for use in only certain applications, the recommended products for use in Electric Toothbrushes are listed below.
