The principle of the touch table lamp is that the internal installation of the electronic touch IC and the lamp at the touch of the electrode sheet to form a control loop. When the human body touches the inductive electrode piece, the touch signal transmits a pulse signal to the touch sensing end by pulsating direct current, and then the touch sensing end emits a trigger pulse signal to control the turn-off, and if you touch it again, the touch signal is transmitted to the touch sensing end by generating a pulse signal from the pulsating direct current, At this point the touch sensor end will stop emitting a trigger pulse signal, when the AC is over 0 o'clock, the lamp naturally extinguished. However, sometimes after the power outage or voltage instability will also have a self-lit situation, if the touch receiving signal sensitivity is excellent paper or cloth can also be controlled.
