How to connect sockets and a switch to three wires?
How to connect an outlet block and a single-key switch, if there are 3 phase wires and two not clear minuses from the wall, I connected the switch but I don’t know what to do with the socket. The phase is the blue wire in the image
If you have a phase, then there can be no minus. Maybe zero? Or do you think that zero, because there is no phase?
Connect as always, it is possible that these two wires have the following purpose: phase and zero incoming and outgoing phases from the switch to the lamp. If this is the case, then connect the phase and zero in directly to the outlet, also the phase to the switch and the outgoing wire to the lamp also to the switch.
Or do you not understand where to get the fourth wire? A jumper from the switch (or from the outlet To the switch. So in the photo it is (red as I understand it). What then are you asking?
By the way, why is the blue wire in phase?
