I am replacing a light switch that contains two modules ie two gang two way and each module is labelled “Common, L1 & L2” and works perfectly this way and with the other switch. All have one or two wires in each connector.
However the replacement is a single module labelled “L11, L1, L12, L21, L2 & L22”. I am completely fixed and tried numerous combinations.
So my question is on the new module if I take the old module as a and second as b and new as c where does a-common go in c etc
