ABSTRACT:
A telephone sterilizer device. The device is used in telephones having a base unit and a handset. The handset is a typical telephone handset that is modified by adding two magnetic switch elements. One element is located near the mouthpiece and the second element is located near the center of the handle. Two corresponding switch elements are located in the base unit so that once the handset is returned to the base set completely, the magnetic switch elements close. Once closed, the sterilizer, a UV bulb, energizes. A thermister monitors the temperature of the mouthpiece and disengages the UV light when a sufficient temperature is reached to ensure sterilization is complete. A safety sensor monitors the temperature to ensure that the mouthpiece does not become too hot, thereby possibly causing a user to be burned.
