I'm trying to figure out the name of the "retainer washer" that is missing from an electrical connection on the bottom of an Atlas O Double slip switch. The copper component holds (pushed on) a ground wire onto a post that connects to one of the moveable closure rails on the switch.
I'm trying to figure out what these components are called so that I can source a replacement.
I've circled the spot where the component is missing from in the picture below. I've also included a picture or another spot that has the component.
Any help is greatly appreciated!
