Hmmmmm, been a while hasnt it?!

Im a little puzzled over the whole "normally open/normally closed" condition of Bally motor switches. I have difficulty expalin the scenario and it would be a lot easier if I knew what a particular metal part is called. I have looked all over the net for its name and I cannot find it, so, im going to call it "the little metal thingy"  %.%

The motor cam has a series of disks which alters the condition of switches depending on whether it is running, or at rest. I am going to assume that the correct condition of a switch will be at its "rest" period. HOWEVER, there is a "little metal thingy" which when it is "pulled", pops down and the whole switch stack drops, further altering the condition of the switches. So, is the normal correct position of switches, regardless of whether the cam is moving or at rest, to be checked with "the little metal thingy" is in pulled in, or not.

I do really hope this makes sense to somone  ^&^
