The touch controller is assembled on domestic chip UP, and unlike the touch controller on AT2313 , operated by a single sensor not providing a smooth on/off. The scheme contains a minimum parts (Fig. 1,2), and with the correct Assembly begins to work immediately, without requiring additional configuration. With a short touch the sensor is switched on(off) the lamp. If you hold sensor is continuously adjustable brightness, status remembered until the next adjustment.
