1.The small-capacitor and long-time timer of touch typeHere is to introduce a new small-capacitor and long-time timer of touch type, as it fixes the LEV on 5-pin of the control terminal in the time-based circuit, so the capacitor can get the time of several hours when its value is not large. The other feature of the circuit is that it is touch control, just touch the electrode plate with the finger, the timer will be triggered and gets into work. (circuit principle) The small-capacitor and long-time timer of touch type is shown in figure 10-1.
