I will adjust them again...I used brand new microswitches with the old blades. WIth the playfield up, the balls in they make good contact....I might need to borrow someone small to fit inside the machine with the playfield down!
Will report back.
older microswitches are usually worn out more and are easier to activate. New switch will be stonger, and will need more pressure to activate. Sounds like you will need an oompa loompa to adjust the switch !
