so I have this array of dimmer light switches. I want to replace the middle 2 with traditional switches (well I want to replace them all, but the middle 2 are single pole switches - the outer 2 are 3 way switches).
Whats going on with the middle 2 switches? Why are there 4 wires going into the yellow screw cap?
I already tried to install traditional switches, but only 1 light would work at a time.
In new switch A, I connected the red wire and the black wire (from the wall in the yellow cap) into the terminals. Then in switch B I connected the black wire (black cap) and the white wire (yellow cap) into the terminals and that switch would not work. I will try again but am I doing something fundamentally wrong? Do these switches HAVE to be connected like this?
OK I have uploaded 2 more images to show all the wires coming from the wall:
