what exactly is happening when a volume dial breaks and starts turning the volume up instead of down or vice versa?

In: Technology

Volume controls typically work one of two ways. The first is that for every time the button is pressed a specific electrical circuit is completed, signaling an increase in volume. The other is similar but uses a repeater, so holding the button continuously increases the volume. There are also configurations that do both. If the mechanism breaks in a way that is causes the circuit to remain in the completed position, the volume will continue to increase. There are other ways this can happen, but I feel this is arguably the most common experience, even if anecdotally. Cheers.

Edit: to elaborate on the fact that I overlooked you specifying “dial”, the position of the dial often relates to current, and turning the dial up increases the current which in turn increases the volume depending on the specific types of mechanisms used in processing the audio volume.
