[QUOTE="SPECIAL LOCATION, post: 551758, member: 250"] Just to add some additional background info that may help you understand the arrangements you currently have... (a) a standard single light switch does NOT need a neutral connection... just a permanent live from the supply and a switched live out to the light fitting... The neutral connection is at the light fitting. (b) for two switches to operate the same light a three core cable is required between the two switches so two alternating switch options are possible. (c) UK cable colours for fixed wiring changed during a phased change-over between 2004 to 2006 Old Live and Neutral 2-core + earth cable colours were Red (Live), Black (Neutral) [New colours Brown and Blue]. Old three-core cable colours were Red, Yellow & Blue.. ALL live! [New Brown, Black, Grey] (d) Though frequently not used, for standard single switches Twin Red or Twin Brown 2core + earth cables are available! But if a two core cable with Black or Blue conductors is used for a light switch they should be over-sleeved or taped with Red or Brown to indicate they are actually Live conductors! (e) Red, Yellow & Blue are ALL recognised as live conductors under the old fixed wiring colour identification. So Every wire connected to your switch is either permanent live or switched live.. No Neutrals needed! (f) The Red cable sharing with the Yellow, and the Black cable sharing with the blue are the two actual switch in & out conductors! Hope that helps a bit? [/QUOTE]
