After the battery is clipped, because the movement of touch stick will make the light source shine to photosensitive tube, and produce light current, the first level 3DG6 turns on, the emitter outputs signal, the singal is coupled to back level by 10μF capacitance, Schmitt circuit is triggered and flipped, it outputs singal to control the gate circuit.
