These colorful square tactile button switches are super easy to use. For electronic projects, you can place them on a PCB for a more permanent setup or use them on a solderless breadboard if you want to experiment. To operate, just press the button, and you'll notice it makes a quick connection. When using them, make sure not to press too hard as it might damage the switch. Also, keep them away from moisture as it can affect their performance. To maintain them, a gentle wipe with a dry cloth can help keep them clean. That's all you need to know to get the most out of these switches.
