Replacement Buttons for a Simple Calculator

This is an easy way to fix a simple electronic device, such as a pocket calculator, that has missing rubber buttons.

You will need:

  • A cheap touchscreen stylus with a rubber tip
  • Masking or washi tape
  • Scissors
  • A pen or permanent marker

Step 1: Preparation

Before anything else, make sure that the calculator responds when you press the stylus into the area where the button should be. You may have to press hard or try a few times, but that probably won't be how it is when you're finished.

Remove the tip from the stylus. On mine, the metal ring unscrewed and I could lift the rubber piece out. You may need to tear the tip out of yours, which is fine, but be careful not to damage it too badly.

Step 2: Making the Buttons

Carefully cut the stylus tip into pieces and place them in the button holes. If one of the missing buttons is long, you may want to put two pieces in that cavity. The calculator should now be able to register a lighter press than when using the stylus as normal.

Step 3: Covering Up the Buttons

Cut a piece of tape long enough to cover the entire button area. Write the label for each button on the tape before sticking it on. Test out the button a few more times to make sure it's working properly, and you are done!
