Description 16mm Illuminated Push Button - Red

A button is a button, and an LED is an LED, but this LED-lit button is a nice combination of both! It's a medium-sized button, large enough to press easily, but not so big that it gets in the way on a project panel. It has a built-in LED that can be controlled separately from the switch action - either for indication or just to look good.

It is made of black plastic with the built in LED 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 like you would with other LED lights.

This particular button is ''normally open''. The two contacts are open as long as the button is not pressed. When you press the button, they are connected. As soon as the button is pressed again, the contact is broken. The LED is separated from the button. This allows you to set the LED yourself to your liking.
