The circuit diagram of the components used: MMCR100-8 9012 9013 3DJ6B as shown in Figure circuit, switch panel it is plastic structure, without any metal parts. When you use as long as the hand touch plastic panel lights to light, some time after the delay, light go off on their own. Delay of the circuit depends mainly on the numeric value of R2, R3, and C2, schematic data delay time is about 1min.
