3. Illustrate the Connections:

   Show the connections between the relay terminals and the external components of your circuit. Use lines to represent wires, and clearly label each wire according to its function (e.g., power supply, control signal, load). Accurate representation ensures the diagram is easily understood. Employ clear and concise labeling to avoid ambiguity.

4. Add Component Labels:

   Clearly label all external components, such as power sources, switches, and loads. This adds context to the diagram and makes it easier to understand the overall function of the circuit. Clear labeling improves readability and makes troubleshooting significantly easier. Thorough labeling prevents potential mistakes during implementation.
