NE556 touch of dimmer circuit

This circuit can realize the brightness of the light by dark brighten (light), by bright dark (the). Use touch components of realize touch control, and so in addition to touch piece outside, still need to plus a touch circuit (can choose sk-ii integrated circuit). Additional, because of bright dark dark brighten is a delayed hige, so need to choose a certain "delays" circuit, therefore, integrated circuit, and the NE556 can use. In addition, the light of the control is generally through the thyristor and the light of the direct connection, realizes to light the hige control circuit. In essence the thyristor and lamp light control of main circuit, touch of + touch circuit + base integrated circuit NE556 subprime circuit of components. NE556 touch of dimmer circuit:
