Panel Mount 10K Log Potentiometer w/ On-Off Switch - 10K Log w/ Switch Wholesale
Potentiometers, or "pots" to electronics enthusiasts, are differentiated by how quickly their resistance changes. In linear pots, the amount of resistance changes in a direct pattern. If you turn or slide it halfway, its resistance will be halfway between its minimum and maximum settings. That's ideal for controlling lights or a fan, but not necessarily for audio controls.
Volume controls have to cater to the human ear, which isn't linear. Instead, logarithmic pots like this one increase their resistance on a curve. At the halfway point volume will still be moderate, but it will increase sharply as you keep turning up the volume. This corresponds to how the human ear hears. Using a log pot therefore gives the effect that a setting of full volume on the control sounds twice as loud as a setting of half volume. A linear pot used as a volume control would give large apparent changes in loudness at low volume settings, with little apparent change over the rest of the control's range.
The built-in switch makes it perfect for audio projects where you want to control both power and volume of a monophonic signal.
