Was about to replace a stair switch that has 2 way (top stairs/bottom stairs) function and found that the red Live from the 3 core strap and the black neutral from the 2 core switch from junction box cable were not connected into the switch but to each other via a plastic connector.
looking in the book i see that it suggests-
red from strapping cable goes to common, yellow to L1 and Blue to L2.
The 2 core switch cable from the junction box would then have it's red going into L1 and the black going into L2.
If i replace the socket should i wire it up as suggested in the book or is there a reason that it was done the way it was originally with the plastic connector and should i retain this instead.
