Aluminum alloy plum knob
The knob itself is very delicate. Unlike pressing a switch, it can only output one quantification. The knob may correspond to several quantifications, or a limited range such as '0-10'. For example, a common volume knob will allow users to adjust arbitrarily within a certain value, and a slight turn can get the desired volume, which cannot be achieved by pressing the up and down buttons all the time.
