🔍 Key Concepts

• Review the difference between a normally open (NO) and normally closed (NC) contact in schematic diagrams. • Understand how a limit switch is shown when it is mechanically held in the opposite state from its normal condition. • Compare the added symbol markings (such as wedges or actuators) that distinguish a simple contact from a held or actuated contact.

💭 Think About

• Look closely at symbols 11–14 and first decide which ones are clearly NO and which are NC before worrying about the "held" part. • For the symbols that look NO, ask yourself: which one includes an extra mark indicating it is kept closed by some force and will open if that force is removed? • Consider how the symbol would change if the holding force failed—would the contact return to the open position? Which drawing suggests that behavior?

✅ Before You Answer

• Verify that the chosen symbol shows contacts that are open in their normal state, not closed. • Confirm that there is an extra mechanical indication (like a wedge or actuator) showing the contact is being held in the closed position. • Make sure you are not picking a symbol that represents a simple NO contact without any indication of being held or mechanically maintained.
