Fuse Schematic Symbol

The schematic symbol for a fuse is:

This is the standard and most common type of symbol found for fuses in schematic diagrams.

Example circuit

An example circuit with a fuse is shown below:

You can see the fuse in series with the lamp on the right. Since a fuse's job is to protect electronic circuitry, it will break open if the current going through it exceeds a certain level depending on what current the fuse is rated for. If its rated current value is exceeded, the conductive metal inside of it will break open, so that the current cannot go across to damage the circuitry, which in this case is a lamp.
