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.

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.

A button is a button, and a switch is a switch, but this LED illuminated arcade buttons is in a class of its own. Its the same size as a 'standard' 30mm arcade but has a built in LED that can be controlled separately from the switch action - either to indicate or just to look good.

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.
