Sorry, I've got another quick question before I order some parts. If I want to use Goldleaf buttons, and select the harness type for 2.8mm switch connectors, will all of these buttons be wired for Goldleaf buttons?

The reason I ask is for player start and coin buttons, and whether I need to order
all Goldleaf buttons to be compatible with that wiring harness.
Also, what are 1A/1B/2A/2B used for? Could I use these for pinball flippers?
