Custom keys

Good morning,

I am doing an arduino based calculator and need to have custom labels for the keys, so I would like to ask if anyone knows of a company that makes custom keys for calculators ?

Other option would be those transparent buttons that you can stick a label inside it, like the ones in the link below. But I cannot find those anywhere. :frowning:

Thanks in advance.

Best regards,
Pedro

If you use keyboard switches (assuming the size is acceptable to you) you can get customized printed keycaps for a fairly reasonable price and you can use some super sweet mechanical switches. I switched from a cheapo dome switch USB tenkey to a nice one with Cherry MX blue switches and it really makes a huge difference for bookkeeping.
