I just finished restoring a Williams Flash pinball. As on all older bally/williams (at least that i have seen) with double flippers on one or both sides, the activation switch for the secondary/upper flipper is located on the lower flipper eos. This will result in a small bit if delay for the upper flipper so it's kind of hard to get the timing right. For some reason the lag was more than usual on my Flash upper flipper and i could not seem to get the adjustment of the switches correct to get the lag down. Then i thought about it for a while and came up with why not have the secondary flipper switch located on the flipper button just as on newer machines. You'd get the same action as later pinballs with staging and no noticable lag. I relocated the switch and sure enough it works great, no lag! Is it somehow not electronically correct to make this mod cause i can't seem to come up with such a reason?

Does anyone know the reason why they put the flipper activation switch on the lower flipper eos instead of a second switch on the flipper button?

Of course, on some other machines like paragon or harlem, it would mean you could stage and cradle up and perhaps make the game easier. Not sure, but maybe it would be a nice change in competition to alter the gameplay.

Ah ok. I don't notice any weak flips, if anything, the upper flipper became a lot more powerful actually, and I'm pretty sure it's not just because of the lag that went away.
