Sasha Posted September 24, 2009 Report Share Posted September 24, 2009 http://lividshop.com/hardware/rubber-key-pads.htmlProduct DescriptionOur translucent white silicon rubber keypads have 64 buttons plus 2 function buttons on the bottom. Each button has a hole on the bottom to allow for LED illumination. The buttons have a conductive backing for creating a contact to a circuit board. The button pad can be easily separated with a razor blade (at your own risk of course) to create a different layout.These are the same buttons we use on our Ohm64 and block controllers and do not have any printing on themPad size6.625†- width7.5†- length.75†- heightButton Size0.5†- length0.5†- width.625†- high4x1 versionhttp://lividshop.com/hardware/4x1rubber-key-pads.htmlOur 4x1 translucent white silicon rubber keypads have 4 buttons .

Phattline Posted October 9, 2009 Report Share Posted October 9, 2009 I am from austria, and I want some... but bevore- to be sure the facts?:one square: 1,58cm x 1,58cm8x8 buttons: 16,82cm x 19,5cm19" frontplate space is 43cm43/16,82= 2,55 - too bad only 16 steps...---So I only have to etch my PCB, and this buttons work on the blank cu (copper, kupfer) PCB? Or do I need some "lamination"---One Problem maybe you see here:http://lividshop.com/catalog/product/gallery/id/45/image/90/The Contact space is a closed circle, that meens, you have to make a double sided board...on the upper side is then the BUTTON contact routing, on the lower the LED circuit.... that meens, it will be harder to do that DIY ???

sineSurfer Posted October 10, 2009 Report Share Posted October 10, 2009 On personal experience, this type of contacts against bare cooper tend have duplicated triggering or fail to make contact sometimes so you need way to improve the contact, there's this material to do the work, haven't tested myself but I've seen it used with good results it seems:TINNIT BRIGHT TIN PLATEAlternative for the closed circle:You could cut away some of the contact circle, just enough to avoid touching the led traces, would be wise to protect those traces too (nail polish comes to mind).Another thing to consider, with a top layer only diy pcb you'll have to use surface mount components only.Also, seeing the photo again is not clear if there's actually a hole on the pads to be able to use regular leds, if not, maybe holes could be drilled.
