Struggling to change 2 light switch to 2 dimmer switch for LED's Ask questions and find answers to many subjects relating to electrics and electrical work

I hope someone can help. I've got a double light switch - one for kitchen down lighters and one for dining room ceiling light. I bought a LED double dimmer switch to replace it. (LED, as the kitchen is LED and will be using LED in dining room). The existing switch is a L1/L2/L3 combo. The new dimmer switch is L1/L2/COM (Squiggle sign) - separate switches. On the existing, all the brown live wires are connected in a certain way. I tried replicating it exactly (L1 = L1, L2 = L2) - did not work. Then I tried L1 = COM, L2 = L1. Also didn't work.

What am I doing wrong, or is the switch not the right one?

Pictures for better clarification attached.

Thanks in advance!

You connect it the same as your old switch is connected.
There is one differance. L1 on the old switch is ~ on the new switch
So on the new switch no need to use L2.

Before you do anything else, two questions.
1) Can the LED lamps be dimmed? (Not all can)
2) Can your dimmer dim LED lamps? (Not all can)

It does seem odd that on your old switch both L1's are connected to each other, I guess we will never know why.
