Using this digital push button is a breeze. First, check that the power supply voltage is within the 3.3V - 5V range. Then, simply plug in the cable following the 'plug and play' method. You can easily tell if it's a digital sensor by looking for the 'D' in the corner. The illustrations on the back will help you understand what the button does. For added fun, you can take off the plastic cap. When it comes to maintenance, keep it in a dry place and avoid exposing it to excessive dust or moisture. The long - lasting pressable life means you can use it often, but be gentle while pressing the button to ensure its durability.
