Thanks for those ideas. I really would like black buttons with white lettering, but the only way to get translucent buttons is in white. I guess I could consider reversing it, and infilling the engraving. My initial experiments didn't work well doing infilling, so I did one using a black auto

I doubt it. Some companies won't talk to you unless you are willing to spend $50k, the next may want $1k, its a gamble. They do put an stl of the button on their website, I guess if I had a two color 3d printer I could do it that way? On Sat, Dec 8, 2012 at 8:36 AM, Mark Wendt

I don't see an easy way to make multicolored silicon rubber buttons, though. I shouldn't even open my mind to doing silicon, its one of those things that is tempting though. I guess I could try making my own buttons with translucent black acrylic. I am stuck using something that will fit on top

I painted some of these http://www.digikey.com/product-detail/en/1WD16/679-2144-ND/2034700 buttons today, and engraved them, but find that the paint is not curing like I would like (not very durable), and the paint is soft enough that they did not engrave very nice. Not only that, these are

I reverse laser engrave legend plates, device labels, operator panels and sometimes prototype membrane switches. I've also done front surface engraving. I assume that's what you're doing on these switches. The big problem with that is that fingers activating the switches will erode the
