Simple I thought! Wrong. My old light switches are cabled in red and black and operate one common 2 way light and 1 other independent light each. The upstairs switch has three connectors at the top marked ABB and three at the bottom marked AAB. Three cables come into the box - cable 1 has the red line not connected and the black line goes to the B connector on the bottom row (AAB). Cable 2 has the red line going to the A connector on the top row (ABB) and the black line goes to goes to the first A connector on the bottom row (AAB). Cable 3 has the red line going to the middle B connector on the top row (ABB) and the black line goes to the other B connector on the top row (ABB).
The switch downstairs has the same AAB and ABB connectors but the wiring is different. 2 cables come into the box. Cable 1 has the red line going to the B connector on the top row (AAB) and the black goes to the outside B connector on the bottom row (ABB). Cable 2 has the red line going to the outside A connector on the top row (AAB) and the black line goes to the middle A connector on the top row (AAB). There is also a red line connecting the B connector on the top row (AAB) to the A connector on the bottom row (ABB).
My new switches are from Focus and have 2 banks of connectors with 3 openings in each. The openings are not marked in any way I can read although there seems to be one marked with 50Hz, one with BSEN 60669 and one marked GB 18916. I think these are just manufacturing numbers.
Can anyone please suggest a safe wiring layout for each switch so that I don't blow the fuses or myself up. Thanks
