Using this arcade button is a breeze. First, find a suitable indoor enclosure and mount the button on it. It's quite easy to install, so you won't have any trouble. If you choose to use the optional LED, just connect it to a power source of up to 12V. Remember, because of the button's design, the LED won't light up the button face evenly, but it still adds a nice touch. When you press the button, it'll activate the microswitch and complete the circuit. As for maintenance, since it's not waterproof or weatherproof, keep it away from moisture and water. If it gets dirty, you can gently wipe it with a dry cloth. Don't use any harsh chemicals as they might damage the plastic cover or the LED. Enjoy using your arcade button for hours of gaming fun!
