Review on High-performance Vibrating Concrete Vibrator for Enhanced Control and Governor-like Vibration by Anthony Heinrichs

Good switch. I'm only taking off a star because there is no wiring diagram. The colors of the wires are for China in my opinion. I'm not sure if they are standardized there. I followed the same color coding as my cement vibrator which also shipped from China and this is how it works. Brown = hot (black in US) Blue = neutral (white in US) White = ground (green in US) If you're using a concrete vibrator, it'll only work between 4 and 7, so keep that in mind.
