Electric Toothbrushes Achieve Much Greater Reliability Using Reed Sensors

Introduction

For years manufactures of electric toothbrushes have used mechanical slide switches to power the toothbrush on and off.  The mechanical slide switches are subject to very harsh environments having to deal with chemically active toothpastes, acidic saliva, and running water at various temperatures and acidity/alkalinity levels.  This environment attacks the electrical contacts in the slide switch and in many cases, after a short time the slide switch fails to turn the toothbrush on and off.  Going to a Reed Sensor has eliminated this problem.
