+# 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.
