How to connect a light switch if two wires stick out from the wall?

Yuri asks:
It is necessary to change the switch in the kitchen from the wall, only two aluminum wires sticking out, how to assemble it correctly, the letters L and L1 on the switches
The answer to the question:
Hello! The wire on which the phase to the terminal is marked with the letter L, and the one that goes to the lamp (there is no phase) goes to terminal L1. In general, it does not matter, even if mixed up it will work the same.
