Choosing The Right Knobs and Pointers for Your Electronics

Most consumers may not think twice about the types of knobs that there is on an electronic component, but there is a niche audience that is particularly sensitive to having suitable, ergonomic, and aesthetically pleasing knobs for their device or machinery, be it as simple as a knob for an audio stereo system or a knob for an avionics control panel. In the cases for the latter or items similar to it, the type of knob that is placed on there is crucial. The first step in selecting a knob for such enthusiasts is to select a potentiometer shaft that is most suitable for the knob fitting.

While some may argue that selecting the potentiometer shaft first is a less efficient way of shopping for a knob you need. This is because you have to deduce the answer to several questions including those parameters that you would need for choosing the knob. Such includes can look like “what if you’re looking for a knob that’s different?” or “what if that knob will fit only one particular type of shaft?” It might appear to be irrational yet organizing the handle over potentiometer in the particular procedure bodes well (much like indicating your fenced in area before your PCB). Don’t let hidden potentiometers – that users won’t see – dictate the look and feel of the knobs they will see and touch. 

Utilizing More Than One Range of Knobs

What happens if it’s not a knob that you need, but a dial, and on top of that, what if the machinery that you need it for is requiring a digital dial? In this case, you could certainly acquire a digital dial, so long as you understand and appreciate the difference that there are between digital and non-digital. Basic digital indicators are priced competitively with high-quality dial indicators, and provide data output as standard features.
