I am getting started on the power side of my mill. All of my contactors have these small black boxes mounted on the front.
After searching several sites, I can't come up with anything.
Usually that is where the (plunger????) is.
Are these to make a lamp come on when the contactor is engaged? Or prevent the contactor from engaging until something else is kicked in?
I didn't take a pic of mine so here is a modified catalog pic. Can't remember if mine have 1 or 2 wires?
Just checking to see what they were in case it affects how things need to be wired.
