alt Hacker NewsHair dryers normally have 2 controls, one to adjust how much air it blows, and another one to adjust how hot the jet is.
When they're off, they don't blow any air so it would make sense to me to decide that the button to turn them on is the one that controls how much air it blows. It goes from 0 to 1 to turn on, so you just learned that that button changes how much air comes out of it.
But no, most of them do the opposite. So, you turn them on with the temperature control. The action is: no air, yes air, air gets super-hot if you keep pushing the button.
I can't find any modern air dryers where they get this right.

I imagine it’s similar to why a fan starts at max. Eg: 0->3->2->1
Something technical made it easier to implement.
The Dyson Supersonic?
Possibly a consumer air dryer problem, something-something safety. Check professional ones like Parlux, the one I checked has 2 dials: airflow and temperature. Turns on by air dial. They are also conveniently under the thumb so you can adjust without looking.
