Potentiometer 6Pin Shaft WH148 Amplifier Dual Stereo 5K

This potentiometer is a two-in-one: it's a log taper 5K ohm potentiometer, with a grippy shaft and it comes with an on-off switch. It's smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2" apart with pin-points, so you can plug it into a perf board. Note the spacing on the switch/pot pins is 0.2" so it won't work in a solderless breadboard as nicely unless you bend the switch pins out of the way. Once you're done prototyping, you can drill a hole into your project box and mount the potentiometer that way.

Potentiometers, or "pots" to electronics enthusiasts, are differentiated by how quickly their resistance changes. In linear pots, the number 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 the power and volume of a monophonic signal.
