ABSTRACT:
An electronic clinical thermometer which includes a temperature sensing element for sensing body temperature and converting the sensed body temperature into a corresponding electrical signal, a measuring unit for converting the electrical signal into a digital signal, an arithmetic unit for computing body temperature on the basis of the digital signal, a display unit for displaying the computed body temperature, a battery for supplying each of these loads with electric power, and a magnetic reed switch, having a break-type contact, connected between the battery and the load. The electronic clinical thermometer, in combination with a carrying case, includes a magnet which opens the switch contact of the magnetic reed relay when the thermometer is placed in the case.
