I'll be starting doing industrial work on a few weeks so my friend let me borrow a motor controll book.
Started to read about contractors and motor starters ,
It shows a pic of a contractor with auxiliary contacts on it and says auxiliary contacts
May be added to a contractor to form an electrical holding circuit .
In the line diagram it shows stop and start puch buttons
Controlling a starter , the aux contacts are in series with the start button
I don't understand what aux contacts do could someone explain some senerios were u would use
Aux contacts and are their only normally open or do they also make nc auxiliary contacts aswell
and say if you have a norm open push button when you manually puch it does it go back to norm open
when your finger comes off button
