A switch and an LED come together beautifully in this 16mm illuminated pushbutton. It's a medium-sized button that's easy to press and won't clutter your project panel. With a built-in LED, it can be controlled independently of the switch action, adding both functionality and style.
The button has a black plastic body with the LED inside. There are two contacts for the button and two for the LED, marked + and -. The LED has a forward voltage of about 3V, so connect a 220 - 1000 ohm resistor in series to your 3V or higher power supply, just like with any other LED.
This white button has a latching on/off function. The two switch contacts can be connected or disconnected. When you press the button, it switches states like an on-off switch. The LED is separate from the button, allowing you to customize its lighting, like having it light up when on, off, or always lit.
Using this 16mm white latching on/off illuminated pushbutton is a breeze. First, when connecting the LED, make sure to add a 220 - 1000 ohm resistor in series to your 3V or higher power supply. This will protect the LED from too much voltage. The button's switch has two states: connected and disconnected. Just press the button to switch between them.
When it comes to the LED, you can get creative. You can make it light up when the switch is on, off, or keep it always lit. This gives you a lot of flexibility for your project.
For maintenance, keep the button clean and dry. Avoid using harsh chemicals on the black plastic body as it may damage the finish. If you notice any issues with the switch or the LED not working properly, check your connections first before assuming there's a problem with the button itself.
