A component is an electrical device that consists of one or more symbols.

For example, a relay coil and contacts. The main symbol is the relay coil; the individual contacts are subordinate symbols.

main and subordinate symbols

For example the main symbol of a component is labeled (reference) K5. The subordinate symbols would be labeled parent reference + dot + number, for example K5.1, K5.2 etc.

In other words, all symbols of a component have the same reference before the dot.

The subordinate symbols are normally not shown in the bill of material. If you want them to be shown, check the Show subordinate symbols on the bill of material dialog window.

If you follow this method of labeling, a reference table appears beside each symbol that is part of a component.
