The red one is permanently live andI'm about to replace a socket switch. The electrics were installed in 1970 so pretty old. One of the wires is black with a part brown cover, the other red. Which is the live wire?
Then it doesn't matter which one is which.Sorry, it's for a light switch!
Red-Com
Black with sleeve-L1
it's the correct way to do it!
That the standard method used to install a one way light switch is to connect the permanent live to the com terminal and it is also good practice.

They are the Lives, when on, which share a Common supply.So what does the L in L1, L2
