Where to find RGB button

Post by obust » Tue Mar 10, 2020 12:31 pm

Hi all,

I am new to DIY and would like to build a eurorack sequencer.
For the design I have in mind I would need RGB button likes the ones used by Intellijel (e.g. on the Quadrax but I am struggling to find any.
Does anyone know what these are called and where to find them ?

On a more general note, where is a good place to look for classic eurorack parts:
- (LED) sliders
- knobs
- encoders
- (rgb[a]) LEDs

Thanks for the help

nice rgb buttons are kind of hard to do in my experience. would also love to know which part intellijel uses here or if its a custom ws2812 build.
edit: intellijel employee on their forum says they're custom made.

what you wanna search for is "rgb illuminated pushbutton" or "~ tactile switch"
https://www2.mouser.com/Electromechanic ... weZ1y876pr

for a sequencer you could also look into the adafruit trellis thing:
https://learn.adafruit.com/adafruit-neo ... d_products
those use the WS2812 rgbn leds which aree also your choice for the RGB leds you look for, easily adressable via any MCU.
those also exist in classic 5mm led shape.

i am pretty sure we'll see some more ws2812 based smaller buttons soon,it's suchh an obvious market. if anybody on here feels like designing a chainable 1-led version of the adafruit PCB, i'd buy a ton! it's super simple, and you can get anyshape of elastomer silicone rubebr pad thing quite cheap or print it onyour friends 3d printer.

for general euroack slilders, pots, jacks, def go to www.thonk.co.uk to get an overview of the most popular parts.

rotary encoders, for the afforddable 24-30 ppi ones most people use bourns PEC11 series but the slightly more expensive ALPS equivalent feels much nicer, more like a classic pot. higher resolution encoders get really expensive.
also look into endless analog potentiometers as an alternative to rotary encoders. i just learned that thats what NI uses on their Kontrol/Maschine hardware.

Is it this one?

Highly PB615303HL-7

same as the ones on the 4ms SWN?

Good for them and too bad for me :(

I went through the pages and nothing seems to fit the bill...
a chainable 1-led version of the adafruit PCB
Although probably too big for the eurorack market, that would already be a good alternative

Do you have a link ? Google doesn't recognize it. The 4ms kind of led button would work for me as well !

I usually look for clear buttons or knobs. then I look at surface mounted LED's. you can mount the LED's on the other side of the PCB with a drill hole for light. there are surface mount packages that shine down instead of up. sometimes you can stack SMD parts vertically on the same side of the PCB. the height of an LED can be < 1mm. if your knob has a cavity under it then you put it there.
