Description: This is a simple LED-illuminated tactile button with a red cap. It's just like a basic tactile button, but it lights up red! 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.

  • The coolest thing in the world would be an RGB LED version of this button.

  • So are these TSD1265 or TSL12121? You have the datasheet from the TSL12121 and the drawing of the TSD1265. Having just got hold of a technical drawing of the TSL12121, it looks like the TSL12121 is 7.3mm from the base to the top of the button, where as the TSD1265 is 6.5mm. Its only 0.8mm difference, but it could be quite a big deal if you’re using these to replace individual worn switches in a unit that uses one or the other type. They also have a big difference in the operation force.

  • i’m having trouble locating this in the sparkfun eagle library. can anyone direct me as to the name / location of the component? thanks

    • Oddly enough, I can’t find it either. You can get a device (package+symbol) I made a while back from: https://github.com/EagleWorks/ I also included a package derived from the LED Tactile Button Breakout (see below), so you have your pick of mine / a semi-official one.

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

    red led juice = 2vdc 50mA

    button = 12v

    button current max = ???

  • For something rated for 12V the LED is awfully smokey at 5V

  • Eagle part, please!

    • Check out the LED tactile button breakout, it should have what you need.

      • please put it in the library?

        • it is in the eagle library, it just wasn’t marked as such, doing that now.

          • Robert, could you reveal the name? I searched and browsed, but couldn’t find it.

            • I don’t know off-hand. If you open the eagle files for the breakout, you can see what it is pretty easily. if you run into further issues, email techsupport@sparkfun.com and they can help you out.

              • Yeah, I did.. but the name was nowhere to be found in the libraries. I’ll shoot techsupport@ an e-mail, thanks :)

                • The Eagle Library has now been updated to included the button. It should be located in SparkFun-Electromechanical.lbr. The device is labeled as SWITCH-MOMENTARY-LEDPTH and the package is labeled as TACTILE-PTH-LED-12MM.

  • I notice on the data sheet that it specifies 12V, 50mA. I assume this is the rating for the switch, which would make this the lowest power switch I have ever seen. More seriously, I assume the switch is 12 volt, and the LED is 50mA (far more likely), so what is the max current rating of the switch, and the forward voltage of the LED @ 50 mA? I can take guesses, but these would be useful things to have in the description.

  • Any chance of getting these (And their sister LED buttons) in RoHS compliant versions?

  • Obviously these switches are made in China (look at the data sheet), but may I suggest that someone at Sparkfun might have spent a short amount of time making the data sheet some what more useful (and better presented) by converting the poor English (and Chinese characters) into something that we can read a little more easily.
    After reading the data sheet I still do not know if these are binary state switches (i.e. either on or off) or if they are instant switches, - please advise.
