Well, I got translucent microswitch buttons for my birthday. They came from centsible amusements. I don't know if anyone else has "reviewed" them, but I had some initial thoughts on mine.
1) You thought X-arcade buttons were short? These are shorter. I had to turn the nut over on every button. I have 3/4" particle board w/formica laminate for my control panel.
2) They are the convex style, and I was brought up on concave buttons. They have a very low profile as opposed to the old-style buttons. I actually like the feel quite a bit, but i do seem to miss a button press every now and then.
3) I think something is messed up with the mold. The blue buttons had a misshaped piece where the microswitch attaches. More of a "crushed" looking part on the very bottom of the button. This does not effect anything btw, i just noticed it.
As far as "lightability" goes, the whole assembly is translucent. I have not yet tried backlighting them in my arcade, but they glow "real purty" with a flashlight. My first thought as far as lighting them is to use a pair of white cold-cathodes. It also looks very possible to illuminate each one by installing an LED in the button (above the microswitch.) I'll need to make sure on that one though, I haven't really looked at the clearance with the microswitch in place.
If you've been thinking about getting these buttons, and have any questions, I'll be glad to try to answer them. Just PM me.
(Sorry if someone has already posted a lot about these, I just thought i'd share. I'm no Kev Steele by any means.)
