Parallel circuit operating like a series connection of
n/o contacts
A series circuit with more than three contacts (n/o contacts)
can be implemented with a parallel circuit of n/c contacts on
a negated coil.
In the CL circuit diagram you can switch as many rungs in
parallel as you have rungs available.
