Need some help with changing a switch (Europe)

[Dilantha]

Hi,
Im trying to replace a bulb switch but im not sure where to place the wires on the new switch.
First image shows the existing socket and on the second picture the right side socket is the new one that im going to use. Any help would be highly appreciated. Thanks.

The two brown wires connect to L.
The black and white each go to a terminal marked with an arrow.
