Light touch variable delay circuit - schematic

Rs L DC dirty drop trigger pull bite silicon SCR conduction, the lights. It consists of ten C. The more people who ask constant discharge, open extension l column Duan Yan lights off when M. When you touch the metal "M I little while when the voltage across the electrical .q TV Division, touch steamed shabu li inch shorter, lower C, both ends of the voltage discharge M also girl, so electric lights time is short, and vice versa r cancer when I change may K. So Shing touch setback time delay n.rriil_ boots close by varying widely cited theoretical calculation, when touch hug one second, ' a charging voltage of 5v, delay IOO seconds; 2 seconds touch Ut, CI charging voltage is 7.5v. delay l40 seconds, 3 seconds break contact resistance, cl charging voltage IOV. la5 seconds delay.
