When drawing schematic diagrams, switches and contacts should be shown in which position?

In schematic diagrams, switches and contacts are conventionally represented in their "on" position to reflect their active state. This approach provides clarity by illustrating the current path in the circuit, which is essential for understanding how the circuit functions under normal operating conditions. By depicting switches and contacts in the "on" position, it effectively communicates that these components are engaged, allowing current to flow.

This representation helps technicians and engineers quickly analyze the circuit and identify how it will behave when energized. While other positions may serve specific purposes in different contexts, the "on" position is standard for schematic clarity and practical application.
