hi all ive read the post with the wiring diagrams in and noting matches mine. sorry if this post has been done before. i changed my hallway and landing switches and have got the wiring a bit wrong. downstairs i have a double switch with 2x 2 core cables black and red one pair feed to the landing the other pair im not sure where they go also there was a short piece of red wire bridging 2 terminals orriginaly. on the landing there 3 wires one red and 2 black one of the black ones goes to the lights and the other 2 come from the hall. how do these need to be wired to get the lights working in the correct way again? i amaware i need a re-wire its on the to save for list. tanks for any information
