schematic diagrams. Some manufacturers employ contactors that use a single set of contacts. A “bus bar” is placed over the connection where the other set would be, as shown in Figure 6. Figure 16 at the end of this chapter includes many other symbols for switches and relays. THE BASIC DIAGRAM Let’s take a look at a “generic” schematic[PDF]
UNDERSTANDING ELECTRICAL SCHEMATICS Part 1
In electrical schematics, the symbols stand for various components in the circuit, and the lines stand for the wires connecting them. The intention of the overall schematic is to show how the circuit functions, not how it actually looks. 1 Refrigeration Service Engineers Society 1666 Rand Road Des Plaines, Illinois 60016 UNDERSTANDING ELECTRICAL SCHEMATICS[PDF]
A schematic diagram acts, in effect, as a map of an electronic circuit, showing all of the individual components and how they interconnect with one another. According to one popular dictionary, the term sche-matic means “of or relating to a scheme; diagrammatic.” Therefore, you can call any drawing that depicts a scheme—electronic, electrical,[PDF]

Understanding and Using Electronic Diagrams 3 This schematic uses the convention of dots to indicate con-nected wires (see the left side of BR1); unconnected wires simply cross each other. To avoid confusion, unconnected wires that cross sometimes have jumpersto show that the wires aren’t connected (see Figure 2). This is an older con-[PDF]
Module 4 Electronic Diagrams and Schematics
Electronic schematics use symbols for each component found in an electrical circuit, no matter how small. The schematics do not show placement or scale, merely function and flow. From this, the actual workings of a piece of electronic equipment can be determined. Figure 3 [PDF]
