Because of space restraints I need a 2x2 matrix
of illuminated push buttons similar to the ones depicted.
What is the precise designation for these? And where can I get them?
The ones depicted are certainly custom made, but I hope
there are some standard parts somewhere.
Also hope they are of the resistive type so that I will not need a decoder.

Searching "Illuminated push button matrix" or similar only
gives terrible results.

PS:
2 hours later: got it. I'm apparently looking for "LED silicone rubber keypads".
