Indicates multiple paths represented by only one line. Letters or names identify indi- vidual paths. Numbers indicate number of paths represented by the line.

Coaxial or shielded cable.

Ferrite bead. (Increases the self-inductance of the conductor passing through the bead.)

Relay. Contact moves in direction of arrow when energized.

Indicates a pushbutton switch with a momentary (ON) position.

Feedthrough capacitor. (Acts as a feedthrough terminal when mounted on a chassis or a frame.)

Indicates a PIN diode.

Indicates a current regulation diode.

Indicates a voltage regulation diode.

Indicates a capacitive (varactor) diode.

Indicates a Schottky (hot-carrier) diode.

Light-emitting diode.

Multiple transistors in a single package-physical location of the pins is shown in package outline on schematic.

Identification of logic families as shown (in this case, ECL).
