Hi, my first post! I'm a fairly competent DIYer, particularly in the plumbing area. Electrics I treat with a great deal of respect! I'm trying to replace a normal 2 way light switch with a 2 way dimmer and am a bit stuck. The rear of the 2 way normal switch has 4 terminals - L1, L2, L3, L4. L2 is unused. L1 has one wire going into it, L3 & L4, each have two wires.
The rear of the new 2 way dimmer has three terminals - L1, L2 and a little arrow with a wavy line going through it! How do I wire the new dimmer please?!
