26100 ABSTRACT OF THE DISCLOSURE An electronic thermometer includes a color coded probe permanently fastened by an electrical cable to a color coded isolation chamber to prevent inadvertent use of a rectal probe with an oral isolation chamber. Red and blue isolation chambers used for oral and rectal temperatures, respectively, can readily be used with one thermometer housing. A connector between the isolation chamber and the housing automatically connects and disconnects the probe and the thermometer circuits when the isolation chamber is inserted into or removed from the housing. Moreover, insertion of the probe into the isolation chamber automat- ically actuates a switch in the electronic thermometer housing to deactivate the electric circuits. Withdrawal of the probe from the chamber automatically supplies power to the thermometer circuits to ready the thermometer for operation.
