Many machines, especially old ones, required the use of relays or contactors in order to make their electrical systems to function.
For example, I wanted to use the box switch that originally came with my lathe. However, because the switch buttons do not hold their position, relays were necessary, I was told. Someone was kind enough to do a drawing for me of the relays in operation, and I bought some ice-cube relays from MacMaster-Carr.
Being an idiot when it comes to all things electrical/electronic, I did not even know what a relay or contactor is.
This YouTube video explains both relays and contactors very well, so that even *I* understand their functions:
