Are there any caps available for these buttons, or am I better off using other, more stylish buttons if I want to make a presentable arduino-based gadget?

The circular hole drilled in their square-section moving part seems to suggest that something can be plugged there, but I can't seem to find caps anywhere.

Thanks for your attention.

  • @Matt I believe he means these: arduino.cc/documents/datasheets/Button.pdf It's linked to by the "ArduinoStarterKit" page of Arduino.cc

  • @Paul - those were what came to mind for me as well, but are ruled out as they do not have a "circular hole drilled in their square-section moving part" May 10, 2016 at 13:09
  • @ChrisStratton Hmm, you're right. I've seen such buttons, but we indeed can't be sure withouth any partnr/picture/specifications.

  • It's the bigger model, 5 breadboard squares wide. Their plunger is square-sectioned, and has a little hole drilled in it. In fact I finally found evidence that they probably have caps, just don't know where to source them : cdn.sparkfun.com/r/600-600/assets/d/7/f/d/b/… - or else the guy 3D printed his caps.

You can use a different type of buttons on with your Arduino, there are some that keep the state or just push button.

The most used are the "arcade" style or the push button on a breadboard.

Just remember to have a pull up/down resistor and add some code to debounce when the button has been pressed. https://www.arduino.cc/en/Tutorial/Debounce

If you want some more custom, you can use a normal push button and add small piece of wood/plastic/metal into the hole and having low friction you will be able to press the button with a nice look and feel.
