<^< Logic Gates | Course Index | OR Switch >^>

The operation of a simple AND gate can be illustrated by connecting two switches in series with a battery and a lamp. It should be obvious that the lamp will only operate when both switches (S1 AND S2) are closed. Furthermore, since each switch can only be in one of the two states (i.e., open or closed) at any given time, the open and closed conditions are mutually exclusive. Furthermore, since a switch cannot exist in any other state than completely open or completely closed (i.e., there is no intermediate or half-open state) the circuit is based on binary or 'two-state' logic.
