Hi,
Look at the attached sample circuit (from the internet) first below. Many cheap devices are being controlled by such power supply like some mains LED lamps, simple colorful flashing LED lamps, torch lights etc. As my experience, in a tourch the power supply was charging its 6V battery of a tourch. I was touching battery's poles but during turning ON and OFF the switch was making little loud sparking and noise (actually all the such power supply makes sparking and noise always during switching ON and OFF or during plugging IN or OUT). And exactly as sparking, I was feeling shocks in my fingers! What and how was that shocking?
