Here is to introduce a ceiling lamp control switch circuit which consists of the CD4518 digital integrated circuit, it can control each line of bulbs. The circuit consists of the power supply circuit, trigger control circuit and control executing circuit, see as the figure. Element selectionR1～R5 and R7～R9 are made of the 1/4W carbon film resistor or the metal film resistor; R6 is the 1/2 metal film resistor. C1 and C2 are made of the monolithic capacitor or the dacron capacitor; C3 is the aluminum electrolytic resistor whose withstand voltage is 16V.
