I think their called orange sticks. https://www.jonard.com/searchresults?term=s-389&reset=y

I use this stick to work on switch blades when filing contacts. This stick allows you to get into the switch stacks with ease. The pointed end can be inserted on the backside of a switch contact rivet which allows a force of pressure bring two contacts together that needs cleaning.

I have a general demonstration on the use of this sticks in one of my you tube videos which can be found at....Vic Camp Pinball: Super Score (unusual findings) with Trip Bank issues part 7
