One way in which electrical components are identified in drawings is by the use of schematic symbols. A schematic symbol either represents a single component in an electrical circuit, such as a pushbutton or motor, or a part of a component, such as with relays and starters. This course covers component representations, component abbreviations, electrical standard organizations, blueprint layout, and blueprint styles.
