Are both things the same

There is a contact under a button of a controller and an electric circuit under the contact. When you push a button down properly then the contact goes down in a straight line and it touches the circuit and that triggers a button press. Normally after you press a button you release it and you allow it to go all the way up and then you press it again.

You can press a button twice very fast. First you press the button once and you get one button press in a game. You don't allow the button to go up after the first button press and you press again while the button is down. If you do it correctly then you will get a second button press in the game and the button is still down when that happens. The result is 2 fast button presses in the game and that happened because you made the contact touch the circuit twice very fast and that triggered 2 fast button presses in the game. That was done on purpose and you knew what you were doing.

Also sometimes you can press a button in a bad way without properly focusing and you get 2 fast button presses in the game because of that. I think that is because when you press a button in a bad way then the contact doesn't go down in a straight line and it goes down at an angle. The first button press in the game is when the contact touches the circuit at an angle. After that the contact becomes straight and that makes the contact touch the circuit again and that causes the second button press in the game. Thus you will get 2 fast button presses in the game when you press the button in a bad way. Is what I said correct?

In both cases the contact touches the circuit twice but the way that you do that is different.

Oh yes, there are many tricks in Minesweeper....
