Knocks out the machine after installing the switch and the socket strip

Hello, it's not entirely clear to me how you put the switch, because the jumpers are thick and you can't see everything. Do you have a two-pole switch or something? Well, should I break the phase and zero? What for? You can only break the phase... what kind of switch in general?

You have at the top left in the second photo jumper on the output terminals of the switch between the upper and lower? If so, then it looks like you close the phase with zero when you turn it on.

In addition, you connect the phase (brown wire) from the cable to the LED backlight directly to the phase coming from the outlet to the switch, and zero from backlight (let's call the blue wire so) connect to the output terminals of the switch from the side of the brown (top) wire, i.e. to phase, and on both the conductors of the LED backlighting cable of the phase, on one constant (brown), on the other (blue) also a phase, but after the switch is closed, it appears will be? What for?

If I correctly disassembled everything from the pictures, then the machine, by definition, should knock out.

Disconnect the switch completely from the circuit and check - if it does not knock out, reconnect and carefully what you are connecting with.
