How to install a Smart Switch

[SamarAhmad]

Pictures of my current 1 way switch are below. I live in the UK and the other side of the small black box didn't have any writing on it.

Hi, I am very new to all this and wanted to know how to install a smart switch and which wires go where. Would all three of the neutral cables go into the N slot. Would the 2 live wires go in L1 and the other live wire in L?

The switch I am going to hopefully buy is:

Thanks.

Much easier to add a 4th blue cable into the connector bloc and only have this new one connected at the switch. No room on the switch terminal for 3....

Most likely, the 2 browns together is the supply, and the single brown is the load (light)

Please take care when isolating the circuit to work on it.
