Which tool can be used to clear foreign materials from a switch?

• A. Broom
• B. Rag
• C. Hammer
• D. Wrench

Answer: (A)

Choosing the right tool for clearing foreign materials from a switch means selecting something that removes debris safely without risking damage to the switch. A broom fits this purpose well because its bristles sweep loose dirt, leaves, and small objects away from the mechanism from a safe distance. The long handle keeps your hands away from moving parts, and the bristles can reach into gaps without applying force that could bend or misalign components. A rag can wipe surfaces but may leave lint or fibers behind and isn’t as effective at reaching tight spaces. A hammer or wrench is for heavy-duty fastening or striking and could damage the switch or cause injury, so they’re not suitable for debris removal.
