I wonder if that switch is operator selection for game to be soccer or tennis. If it is for some other option, I am not sure what it would be for.

That is the same manner that Amutronics has printed in the logic schematics for TV Ping Pong which is a dedicated two-player only pong clone. I don't have any paperwork that matches this particular pcb to help identify what game the pcb is for.
