hello
we have a light switch which is faulty which I need to replace. I was expecting it to look like the smaller image below, i.e. with the Common, L1 and L2 terminals or even with L, L1 and L2 however it is actually as the bigger picture, namely L1, L2 and L3. is this an older style labelling>?
how would this migrate to the newer labeling, i.e. which is Common ? or do simply keep using L1 and L2 ?
