Have you ever wanted to start your widget the same way you start your car? These key switches are the key to making that happen. This simple ON-OFF switch can be used to power up your project with the turn of a key. Two large (2mm x 4.5mm) solder lugs on the back make connecting wires easy.

Wire it up just like a potentiometer and use serial signals to 'turn the knob.' Another handy feature of digital potentiometers is that because they aren't controlled mechanically, they don't have a pre-determined sweep profile.In other words, depending on the way you write your code the potentiometer can 'sweep' in a linear fashion, a logarithmic fashion, or according to any other profile you like. Digital potentiometers can also be used in conjunction with rotary encoders to consolidate large banks of potentiometers into one 'smart' rotary control.
