ABSTRACT:
An electronic thermometer system is disclosed including a circuit for measuring temperature variations, a time measuring circuit, a display for consecutive display of time and temperature, and an automatic digitally timed electronic switch.
The automatic on/off digitally timed electronic switch is responsive to momentary operation of an actuator to turn on and remain on through a predetermined interval including an electronic switch having a latching circuit adapted for connection to a power supply; a drive circuit is responsive to momentary supply of power by operation of the actuator to provisionally begin operating and provide a gating signal to operate the latching circuit; means is provided interconnecting the latching circuit and drive circuit for continuing operation of the drive circuit independent of the momentary supply of power; and a digital timer circuit including counting means is responsive to momentary operation of the actuator to begin counting and provide at a predetermined count an output to inhibit further operation of the drive circuit and deenergize the latching circuit.
