I'm replacing the bathroom extractor fan switch with a new one (the pull cord no longer works)
The new switch only has place for 4 wires - Neutral and Live (Supply and Feed) and the earth. I have 7 wires coming from the ceiling. 2 Blue, 2 Red and 2 Yellow (both with a red sleeve) and the earth wire.
Can I put the blue (N) together and the red (L) together? Where should the Yellow (red sleeve) wires go? In neutral or live (feed or supply)
