Thanks!
It's Hand made, based on wackazong (Ander) idea, to use acrylic. ().
But this rectangular form do not works well, it's very difficult distribute the force applied from any part of the button, to the tactile switch.
My first Prototype was a square button with the tactile on bottom of the square and the leds on center of button. Works Perfectly! I should made square buttons...
I can post the cad drawings of the square buttons if you want, but im warning you: would need a Dremmel (rotary tool) to cut the acryl and to made the outside structure.
As you can see in the photo, i use double-sided copper plates. Its really a good idea, because the copper reflect the light from inside the button.
I need of an idea to keep that shiny aspect of the copper...
In next step of the project, i will make this buttons, but only in summer (this buttons are very laborious).
It's a pun with TraKtor and all their controllers called Kontrol (S1,S4,K1 and F1)...
