2 similar elements act like an OR gate in reverse in a series circuit

I want that they act reversely, for example, one of them does not consume energy, but the circuit is ON, and vice versa
You requirements are still rather fuzzy.

How about two LEDs in reverse parallel connected to one series resistor.
Only one will be on, depending upon the applied voltage polarity.

Yes, but I need two similar elements that work in reverse, and at the same time, the current is maintained in the circuit
Again, just take two pieces of wire. Put them in series with one turned 180°. The circuit is "on".

Or use sufficiently-low-values resistors.

You cannot have no current through one of them and current through the other, which appears to be what you are asking for.
