I've replaced every control button on my A1Up cabinets with these. They really add a classy look and they feel great when playing. The stock microswitches are a bit clicky (imo), so I swapped them with 20 gram Zippy's and there's no going back. Tip: if you want to make them a bit quieter, you can add a tiny o-ring to the plunger stem. It's a bit of a challenge stretching them on (and you may break a few) but, once around the stem and pushed up to the top (under the plunger lip), they dampen the hollow plastic sound of the plunger hitting the body when you mash the button.
