Push buttons
Push buttons are push-to-make switches. This means that they are on when they pressed and off when they are not pressed. A classic example would be the switches on a keyboard.
Push buttons have four legs that are connected in signal-in and signal-out pairs.
To create a breakable circuit we would connect a signal-in cable to the top left at row 23 and a signal-out cable to the bottom-right at row 25.
To override the switch functionality and just have the button work as a connector we would connect the signal-in to the row 23 input and the row 23 output.
