Hi
I want to replace a one way dimmer with a standard one way (using a 2 way switch). Existing wiring is a bit confusing - 3 red wires, 2 to one connection, 1 to the other but seems there's a terminal block for 3 neutrals (all to one connection) and only one earth to back box. Should I transpose double red wires to new switch Com and the single to L1, leaving earth and neutrals as is? Should I do any tests with multimeter first?
Cheers
