Rectifier

Having been ill in bed all day long yesterday because of catching cold, I could not digest some important task, wire arranging putting some rectifier and smoother in the circuitry of newly installed family use vacuum cleaner instead of our professional hi-power device. The purpose of wiring is to activate automatic running when the suction end handle was pulled by the assistance as it had been originally.
Unfortunately any original electric and mechanical relays are not capable because of the difference of the voltage and phases. This is why I'm obliged to make an unnecessary efforts now.
Thank to the trouble of the noise and vibration pollution, I studied much about the difficulty to control air flowing in the long way duct.
