In schematic diagrams, a switch that is not energized is depicted in which state?

• A. De-energized state
• B. Energized state
• C. Active state
• D. Idle state

Answer: (A)

When a switch or relay coil isn’t being powered, it is depicted in a de-energized state. Without electrical current, there’s no magnetic force to move the contacts, so they stay in their default, resting position shown in the schematic. Energizing the coil applies power, causing the contacts to move and the circuit to operate, which is the energized state. Terms like active or idle aren’t the standard labels for this context in schematics, where the focus is on whether the control element is powered and how that power changes the contact position.
