The rear defrost switch if in center console is threaded. The wipper speed switch in center console is threaded.

Except they have graphic icons on them.

Is there a knob that doesn't have an icon?

Wiper speed switch in EU version as far as I know.

US versions have a text there.

Some switches (lights, cigar.lighter) could have as well but with the text/symbols being removed by usage or purpose.
