tch S. vs loses gate trigger current, when the AC zero crossing that is turned off, the lights go out. So turn off the lights and turn on the lights and ordinary bedside lamp switch is no different. But the connection bedside lamp switch S electric cord string with a high value resistor Rl and R2 isolation, even if the power cord is broken even children nibbled switch lead wire insulation foreskin, or switch into the mouth, will not cause electric shock.
