Replacing normal single switch with dimmer Ask questions and find answers to many subjects relating to electrics and electrical work

Hi, new to this forum but would be very grateful for some (I hope) simple assistance.
I am replacing a normal single switch with a dimmer. I've done a bit before and am OK with wiring, but the original switch only has brown connections and the the blue are joined together in the box (which I think is OK).
I'm not sure which connections go where. Any help would be really gratefully appreciated.

The three browns should go into the terminal marked ~ and the remaining single brown should go in the terminal marked L1, but since the terminals are too small for 3 wires, I would suggest you buy some 5A connector strip (Or wagos) connect the 3 brown wires together (just as they are in the switch) Then run a short (But same size, probably 1mm) from the 3 brown wires to the switch ~ terminal, and as I previously said, the single brown wire to the L1 Terminal.

Suggestion.
1) Buy a "wago basic starter box" of connectors, very easy to use and you will never regret it.
2) Move the single brown first, that way you know all the 3 brown wires must go together.

Thank you SO much for going to the effort and spending time to reply. All of that makes perfect sense. I'm very grateful!
