Using this arcade button is easy. First, mount it on your desired enclosure. It fits well on most types. Then, if you choose to use the LED, connect it to a power source up to 12V. When you press the button, it'll activate the microswitch. Remember, this button is for indoor use only as it's not waterproof or weatherproof. To maintain it, just keep it clean and dry. If the LED doesn't light up evenly, it's normal because of the button's design. Don't try to expose it to water or harsh weather conditions, or it might stop working properly.
