Description: This is a simple LED-illuminated tactile button with a clear cap. It’s just like a basic tactile button, but it lights up blue! So now you can get visual feedback, or light up your project. These have a 12mm body and are rated for 50mA. They don’t easily fit into a breadboard, but check below for a breakout board. We also have these in a a variety of colors, check below to see the others.

  • I want a button to light up then turn off when I hit it, would this be a possible solution? Can’t get a read from the gibberish datasheet

  • The data sheet contains priceless verbiage such as “Operating switch is unhindered, rhythmed , and there is not palpable clag.” and “…no serious defects such as very serious shrink, scarcity, fleck, disrepair, transmutation, etc.” Transmutation?

    • The Palpable Clag were a 90’s indie gargage band.

    • Transmutation is a mispelling of Transmogrification, which means that 1/100000 buttons, when pressed, will instantly turn the user into a Snipe.

    • Engrish.

    • Yeah, the data sheet is pretty much useless. No pinouts. No forward voltage drop rating for the LED. At least we know how well it will hold up to SALT SPRAY though! LOL!

    • Transmutation is creating a valuable element such as gold, from cheaper elements. But you have to put so much energy into colliding the atoms that it would cost more to make it, then dig it out of the ground! So if only the button could produce gold or another valuable Element!! Then sparkfun would be selling another awesome product!!

      • That made me think… An uncontrolled nuclear reaction (Read: nuclear weapon) with a byproduct of gold?

  • since sparkfun isn’t doing a good job of providing data for these buttons… this seems to work best for me:

    blue led juice = 3vdc 10mA

    button = 12v

    button current max = ???

  • “Assembly of parts has no badness"
    "Position to maximum moving distance shall be measurement"
    Best two quotes.

    • No, the best quote is this one, “Nate hoped for a website where he could easily find parts, where he could see clear pictures of what he was buying, and where he didn’t have to scour for hours to find data sheets and documentation - but that website didn’t exist.”

  • It’s a shame this has a clear lens. I can see applications where it’d be valuable to have the color of the button in the unlit state match the color of the button in the lit state, like the other buttons in this series.

    • In the off state, run the LED with a low duty cycle PWM. Then it will be dimly lit for off. Once pressed, set the PWM to full-on.

  • What kind of led is build-in into this buttons ? I think it’s no plcc6 ?

  • I tried the recommendation by “joshl” and it worked.. I used 5V and a 270-ohm resistor. Seems okay - decent brightness.

  • I can’t find the max voltage rating for these? if I’m using 5v, would I just use a 330Ω resistor?

  • Looks to me we can connect them so that the LED lights when the button is pressed, but will we suffer voltage drop issues from the LED?
