    Im trying to make something so that it needs 2 constant electric currents to do operation X. How can I make it so not only one will turn it on?

    Hm. Maybe what you need is an AND gate. (What it does is if two wires both get sparks, third one gets spark by result)
    It's made by this:
    - is Metal
    = is PSCN
    + is NTCT
    . is NONE
    -------=
    ........ + = ---------
    --------
