We've got plenty of round and square buttons, but these LED Illuminated Triangle Pushbuttons are welcome to the party. These make us think of 1960's or 70's Sci-Fi control board buttons. As everyone knows, triangular buttons are the most retro-futuristic of all button shapes. Get 6 of them together for a cool hexagonal arrangement, or just have one triangle at a time.These buttons are medium-sized, large enough to press easily, but not too big that it gets in the way of your project panel. Each button contains a built-in LED that can be controlled separately from the switch action - either to indicate or just to look good. This particular button has yellow plastic coloring.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.The LED this comes with is not diffused; for a better look we recommend using diffused 5mm LEDs instead.The two switch contacts are not connected normally. When you push the button they temporarily connect until released. The LED is independent of the switch, allowing versatile lighting options.See the product diagram.
