IEC Symbols

Looking for help identifying these electrical symbols. Some are light and some are dark. What does that mean? Are they light and dark operated photo eyes? IEC Symbol.jpeg
Others here will have access to the appropriate standards so will be able to give you the definitive answer.
At first glance, the detail looks a little blurry to me but it looks like a switch contact symbol with switched signal at the bottom and + and - at the top - I can't tell whether they're inputs or outputs though. Any clue as to the context? I might guess at some kind of pressure switch or even relay - but that really is just a wild guess not knowing what it is the system is trying to achieve.
