A series circuit with more than three contacts (N/C contacts) can be
implemented with a parallel connection of N/O contacts on a negated coil.
In the easy circuit diagram you can switch as many rungs in parallel as you
have rungs available.

A two-way circuit is made in easy using two series connections that are
combined to form a parallel circuit (XOR).
An XOR circuit stands for an "Exclusive Or" circuit. The coil is only energized
if one contact is activated.
