Specifically, the sensor switch  71  is a capacitive sensor switch, when the user smokes in use of the electronic cigarette, the capacitive sensor switch senses the inhaling air flow and thereafter its electric capacity is changed, which controls the atomizing control circuit to switch on the power supply, and thus the electronic cigarette starts work. As an embodiment, the sensor switch  71  may be an airflow sensor switch, when the user inhales by the mouthpiece  50 ; a negative pressure is generated in the electronic cigarette, thus the air sensor switch produces pulsing signals, which controls the atomizing control circuit to switch on the power supply. 
         [0059]    Because the sensor switch  71  itself is accurately manufactured, and it generally has a special built-in controller, the atomizing control circuit may be directly integrated into the controller of the sensor switch  71  in accordance with this embodiment. As an embodiment, the atomizing control circuit may also be integrated to a sensor control circuit board which is separately set outside of the sensor switch  71  and respectively electrically connected with the sensor switch  71  and the battery  20 .
