Two questions:
Each of the 4 pop bumpers on Gtb 1954 Lady Luck have two switches but only have one wire to each switch. This is a bit different from other later GTB pops that I have seen.

1) Are the switches grounded through the switch stack rather than through a separate switch wire?
2) What function does each switch control (coil, bell, score, etc).
Thanks, Steve

yes, they actually use the screws to route the path (this is why if the get reassembled incorrectly, and a spacer ends up blocking the screws, they stop working).

Can't comment on the functions (don't have a LL schematic), but one is probably EOS.
