The switch AND gate is really just like any other switch circuit but with 2 (or more) switches in series. If any off them are off/open, then the whole circuit is off. In a real life circuit, you may want something to be off unless 2 people in separate areas are pushing a button or something.

There are integrated circuit AND gates that you most likely see in practical circuits, but the switch version is helpful for understanding AND gates.

Basics

All of the inputs have to be high for the output to be high.

For switch based AND gate circuits, all switches have to be closed (on) for the output to be on.

Diagram

AND gates are on/off aka. 1/0 aka. High/Low … etc. digital based circuits.
