Yesterday it was bright, off and then open and not bright! Today I changed the switch, or not bright, the situation 1: switch 1 2 lines have a power no electricity, switch 2 1 line has electricity. Case 2: all 2 switches 3 lines are no electricity! When the switch is not connected! Switch 1 inside a green line is a power, switch 2 of the three lines are no electricity. Switch 1, 2 are a green line 2 yellow line, green line are tied several other lines!
Is the connection between the two control? Two switches have three points? If the wiring is impossible, the six points are not available.
