Adafruit 16mm Illuminated Pushbutton - Yellow Momentary

A button is a button, and an LED is a LED, but this LED illuminated button is a lovely combination of both! 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 -. Connect a 220 to 1000 ohm resistor in series to a 3V or higher power supply, as the forward voltage is about 2.2V.

This particular button, with a yellow body and LED, is momentary and normally open. The two switch contacts remain disconnected until the button is pressed and temporarily connected. The LED can be activated in various configurations, lighting up upon press, or staying illuminated regardless of the button state.

For seamless connectivity, this button is compatible with Arcade Button Quick-Connect Wire Pairs - 0.11" (10 pack).
