Hi, I have just bought a house and the wiring needs re-doing. I have managed to change all switches except for one. Its for the upstairs hall way. I opened the switch and saw there are quite a few wires. There are 2 earth, and 2 sets of black and red wires, each wire consisting of 4 or 5 wires coming out of it. What type of switch would I need or would I use a junction box to connect the wires and the then connect another wire for the light switch?
Hope this make sense.
