Magnetic switches can be really finicky. Get them dialed in, and they're fine. But they need a lot of fine-tuning. And they can be limited in terms of application, because of potential for interference with other nearby parts.

I feel like the current pop bumper design actually works really well. There are still lots of places mechanical switches show up on pinball machines, and they are fine. "If it ain't broke, don't fix it" seems perfectly applicable in the case of the pop bumpers. Pinball machines are expensive enough these days, without having to pay for all the extra R&D plus manufacturing costs that fancier switches would entail.

I agree, for the most part. I like some of the changes, like the power switch's new location, and the latch for the lockbar seems fine to me too.

But it does have the disadvantage that it's possible to close the coin door without securing the lockbox now. I haven't made that mistake yet, but I can't say for 100% that I would never. I see some merit in mechanical designs that force the user into the right sequence of operations.
