Fixes two wires in airlocks not triggering

Boolean expressions don't work in switches.
This mistake was in the code since forever, making two specific wires in airlocks completely useless.

That's fixed now.

What this means: We now have two power wires and two backup power wires, and if one of each is cut, the associated power is down.
This is how it apparently always was intended, but never actually worked in praxis, until now.
