This light switch controls both down up and downstairs lights. Also, I have a second one upstairs that controls upstairs plus bathroom, and there is a single three-way switch downstairs.
There are 8 wires:
- grey wire brown sleeve
- black wire brown wire
- brown wire
- brown wire
- grey wire brown sleeve with a brown wire
- black wire brown sleeve with a brown wire
Six terminals on the switch. One side of the switch is working but the other side won’t control upstairs anymore. I’m in the UK.
