How to connect the Yuba switch 4, a blue wire 4 and a red wire? I turn on one switch, and all the other three switches have electricity, but only one wire is connected, and the others have no electricity. First, you connect one of the lights, two Yuba lights and an exhaust fan in parallel, and then connect the zero line. The four Yuba lamps are divided into two groups, and the live wire is connected to the switch box and connected to four switches. The output lines of the four switches are connected with two groups of Yuba lamps. Exhaust fan, lighting lamp. That's enough.
