On an electrical schematic, all operating controls are drawn in which position?

On an electrical schematic, operating controls are typically drawn in their "normally open" position. This convention is widely used to provide clarity in understanding the electrical circuit's state under standard conditions. When a circuit is at rest or in a default position, these controls such as switches or relays are depicted as they would normally appear when no external force or operation is applied.

By representing controls in their normally open position, designers can effectively communicate the intended function of the circuit and ensure that anyone reviewing the schematic can easily interpret how the circuit will behave during regular operation. This understanding is crucial for troubleshooting and maintenance, as it provides a clear base line of how the system is expected to perform.

For designers, using the normally open representation also avoids confusion about the status of the controls in situations where they may be activated or deactivated during operation, as it grounds the schematic in a known state. This consistent practice helps engineers and technicians visualize and plan for various operational scenarios.
