The XOR in a circuit diagram,
shown as series circuit with 2
changeover contacts:

4.2.8 NOT (Negation, Inverter)

A break contact in the circuit
diagram:
The output status is 1 if the input is 0. The NOT block in-
verts the input status.
Advantage of the NOT block, for example: The LOGO!
does not require break contacts. You simply use a make
contact and the NOT block to convert these into a break
contact.
