I ordered a coin door from Ebay ($20 bucks can you believe it!!!!!)

Can someone help me identify what this switch is for. It looks like it would be a system reset.

Also There seems to be a counter on the bottom of the coin bucket. Anyone know how to reset the counter?


And last is this a standard jamma connection? I've never worked with one before so no idea and if so where can i find specs for what the wires are?

Thanks for any help.
