I have a couple DAB radios with a dial that spins mechanically. The dials spin in steps, not smooth like a variable resistor. They also have a push-button so if you push the button it serves as an /ENTER/ button. What is that kind of knob called? I am struggling to even search for my problem because I don’t know the terminology.
It’s every single one I’ve ever encountered. I suppose you could say I’ve just encountered cheap ones - that could be true.
But I’ve never seen a single one (since the 90’s) that didn’t start failing in short order.
Some just sucked from the word go. Have one in my car that had hardly been used because there are separate controls on the steering wheel. Steering wheel ones are fine, the one on the head unit, that’s rarely used, is failing.
