Where should switches and contacts be positioned in schematic diagrams?

In schematic diagrams, switches and contacts should always be shown in the de-energized position. This standardization helps ensure clarity and consistency across engineering drawings and allows individuals to understand the default state of the circuit when no external forces are acting on it.

By depicting switches and contacts in their de-energized state, it becomes clear how the circuit behaves under normal conditions, and technicians can easily diagnose issues or comprehend the intended operation of the circuit. This convention prevents confusion that might arise from depicting components in various arbitrary or energized states, which could lead to misinterpretation or errors during installation or maintenance of electrical systems.
