2 contacts on the insulator with a “nut”
The contact pad is made in the form of a round washer. On the one hand it has a protrusion in the form of a “nut”, on the other hand it has a recess for this very protrusion. Thus, from individual pads, a contact column of any height with any set of contacts can be assembled on a screw or stud, which can be located both on top of each other and with an offset.
Very convenient thing!
