Adafruit 16mm Illuminated Pushbutton - Red Latching On/Off Switch

A switch is a switch, and an LED is an 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 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.

This particular button has a red body and LED and is latching on/off. The two switch contacts are either connected or disconnected. When you push the button, they will switch from one to the other, like an on-off switch. The LED is separated from the button, so you can make it light up when on, light up when off, always lit, etc.

Compatible with Arcade Button Quick-Connect Wire Pairs—0.11" (10 pack).
