Before the article begins, let's talk about the ballpoint pen. I believe everyone uses it. We use it often in the student days, and now many people use it. Press the ballpoint pen as soon as you press the refill and it will come out. Press it again and retract it. This principle is the same as the self-locking push button switch that we often use. When the switch button is pressed for the first time, the switch is turned on and held, that is, self-locking. When the switch button is pressed for the second time, the switch is turned off and the switch button pops up.
