I am trying to replace a double switch and the wires went everywhere so not sure which goes where.
Double switch contains Outside light (brown,blue, yell/green), downstairs light (brown, black grey). link to another switch (brown, black, grey)
Earths are connected to earth terminal, so okay there. neutral from outside light and 1 grey wire connected in connection block, so i presume nothing else there. i therefore have 3 brown left, 2 black and a grey. The switch i have has 2 commons, 2 L1 and 2 L2's. Cany anyone help me please?
