I have a faulty pull light switch from a house built in the 1970s. When removing the casing i find 3 pairs of wires - please see picture.
This switch controls a light and also an extractor fan. The replacement switch i purchased only has L1, L2 and Common terminals. Can anybody please help me with how I can replace this switch? Did I buy the wrong replacement switch or do I need to introduce some other connections before the new switch?
