Tact Switch 12x12mm 7.3mm

This is a standard 12mm square momentary button. What we really like is the large button head and good tactile feel (it 'clicks' really well). This button is great for user input on a PCB or a good, big reset button on a breadboard. Breadboard friendly!

Rotary Encoder - Illuminated (Red/Green)

Rotary encoders are used similarly to potentiometers. They’re different from potentiometers in that an encoder has full rotation without limits. They output gray code so that you can tell how much and in which direction the encoder has been turned.

This encoder is especially cool because it has a red/green LED built in, as well as a push-button. Look below for the clear knob that goes with this potentiometer.
