Firstly i have a 2 way switch in the hall, the main door has 2 live(Red) and 2 switched live (Black/Red) going in to the socket, Wire A has S/L & L going into the top of switch and Wire B has S/L in L1 and L in L2, at the other end i have one wire with L in the 1 way and a S/L in the 2 way it also has a slimmer red wire with grey coating in the Common! My dimmer comes with 3 connections 1 a curve with an arrow going through it, a L2 and a L1 what goes where?
And could i replace both ends with a dimmer?
