PBS-A-500 On/Off Switch 16mm Illuminated Pushbutton - Yellow Latching
US$2.77
It's a medium sized button, large enough to press easily but not too big that it gets in the way of your project panel. It has a built in LED that can be controlled separately from the switch action - either to indicate or just to look good.

PBS-A-515 16mm Illuminated Pushbutton - Yellow Momentary
PBS-A-515 16mm Illuminated Pushbutton - Yellow Momentary
US$2.77
The body is a black plastic with the LED built inside. There are two contacts for the button and two contacts for the LED, one marked + and one -. The forward voltage of the LED is about 2.2V so connect a 220 to 1000 ohm resistor in series just as you would with any other LED to your 3V or higher power supply.

1438-ADA Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit - v2.3
1438-ADA Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit - v2.3
US$34.92
Instead of a L293D darlington driver, we now have the TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time). It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well. Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.

US$17.42
This button has a domed white plastic cover with a black retaining ring around it. There's an optional LED included that will light up the button. The LED has a built in resistor so you can run it up to 12V but given the massive size and shallow depth of the button, it doesn't illuminate the entire button face evenly.
