Published:2011/7/3 0:03:00 Author:Borg | Keyword: ceiling lamp, control switch circuit | From:SeekIC

This circuit consists of the power supply circuit, the trigger control circuit A and the trigger control circuit B, see as the figure. If K1 or K2 can't be locked, then the power should be supplied independently.Element selection R1 is the 1/2W metal film resistor; R2～R6 are made of the 1/4W carbon film resistor or the metal film resistor. C1 is the CBB capacitor whose withstand voltage higher than 400V; C2 and C3 are made of the 25V aluminum electrolytic resistor. VD1～VD6 are all made of the 1N4007 silicon rectifier diode. VS is the 1N4742(1W、12V) silicon rectifier diode.
