My current light switch are only wired with 2 cables: live (black) + ground (white). These is also a neutral in the box, not directly connected to the switch at the moment..
I have 4 light switch in the box, hence the number of cables shown here. Each switch has only 2 cables. On the picture we see a black & white ones which are coming from one switch. The white cable goes to the red screw, the black goes into the box. Inside the box, there are also 4 white cables all tied together with a screw.
Thanks for your help!
