Just replacing a double switch for the kitchen with a dimmer. On the existing (brass plate) it had the usual earth, L1, L2 and Com (common?).
The new switch has L1, L2 and what looks like a tilda (wavy line) with a arrow crossed through it. Is this the symbol for common?
Also, there is no earth being as the new plate is plastic. The backbox in the wall is also plastic so what should i do with the earth?
