Selector Switch Symbol Autocad: A Guide to Troubleshooting and Design

When drawing electrical diagrams, one of the primary purposes is to aid in troubleshooting. In this context, using a clear and concise symbol for a selector switch can make all the difference in understanding how the circuit functions.

In many cases, a normaly closed (NC) symbol can effectively convey the action of a circuit, even if there isn't a specific symbol available for normally open-held-closed or other complex scenarios. Misleading catalogue descriptions have often contributed to confusion among engineers and technicians.

For instance, option E in IEC world appears to demonstrate the action of a switch as installed, making it a clear choice for troubleshooting purposes. In contrast, option A may not be as effective in conveying the circuit's behavior.

To avoid confusion, it is recommended to draw the switch in its first position and show subsequent positions with dotted lines. The contacts should be represented as solid lines in the initial position and dotted lines in other positions. This convention has been widely adopted and is considered a standard practice in many industries.

The NEMA convention provides additional symbols for normally open-held-closed and normally closed-held-open, which can further simplify the process of drawing electrical diagrams. By using these standardized symbols, engineers can avoid misunderstandings and ensure that their designs are accurately represented.

In conclusion, selecting the right symbol for a selector switch is crucial for effective troubleshooting and design. By understanding the different conventions and symbols available, engineers can create accurate and clear diagrams that facilitate efficient problem-solving and design optimization.
