More confusing is text that does not use capital letters at the start of every sentence. What was posted could take two different interpretations. Without knowing, with certainty, what you are saying, well, that legend is standard electrical symbols for generations (except for the fuse symbol). Either you were saying engineers were using those symbols or saying they were not. It's not clear.
NO and NC contacts do not exist for a SPST switch. NO and NC contacts only exist on momentary switches. Either I am contracting what you posted, or am clarifying confusion for others.
Also every terminal connection typically has a number or letter to uniquely identify each connection.
That is what ECNs or ECOs are for. After a prototype, the shop provides an engineer with corrections to eliminate any confusion or to add any missing terminal identification.
QC is a program for failure. QA means an engineer has attitude and knowledge as taught by W E Deming. Else this confusion only continues. QC is a bureaucracy created by management to fix quality because management is the actual problem.
Bad management creates a wall that designs are thrown over when management, instead, makes decisions from spreadsheets. When management does not come from where the work gets done. Then QA does not exist. Then QC is created by management to mask a real problem.
You may want to consider that job with greater caution. It sounds, in some ways, like you would be hired to be the enemy of a problem that you cannot solve.
