Paths
Example:
The lamp could be an overhead light in a hallway,
and one slide switch would be at each end of the
hallway. Whenever you walk into the hallway you
flip the switch to turn on the light, and flip the
other switch to turn off the light when you leave
the hallway on the other side.

Snappy says: batteries are
widely used because they
are easy-to-use, safe, and
portable.
Whenever you flip either switch (S5), the lamp (L4) will
change (turning on or off).
Operation
This switch arrangement is used to control room lights in
almost every home.
