Using this arcade button is easy. Just press the shiny white domed plastic cover, and you'll hear a satisfying 'beep' sound. It's great for arcade games or any project where you need a big, attention - grabbing button. To install it, simply mount it on your enclosure - it fits most types. When it comes to the LED, you can power it up to 12V as it has a built - in resistor. But remember, it won't light up the whole button face evenly because of the button's size and depth. Since this button is not waterproof or weatherproof, always use it indoors. There's no special maintenance needed, just keep it clean and avoid getting it wet. And when the microswitch inside wears out, you can easily replace it as it's a common arcade microswitch.
