🔍 Key Concepts

• Proper maintenance of electrical contacts in control circuits • Characteristics and effects of silver oxide on solid-silver contacts • Why abrasive cleaning methods (wire wheels, coarse sandpaper, painting) can be harmful to contacts

💭 Think About

• Think about whether black silver oxide on solid-silver contacts is always harmful to electrical conductivity or sometimes acceptable. • Consider what happens to the flatness and alignment of contact surfaces if you use very aggressive tools like wire wheels, coarse sandpaper, or paint on them. • Ask yourself which option describes a method that restores the contact surface with the least damage while maintaining good electrical performance.

✅ Before You Answer

• Verify which choice avoids excessive abrasion or removal of contact material. • Check which method maintains the contact surface shape and alignment instead of deforming it. • Confirm whether black silver oxide on silver contacts is a conductor or an insulator before deciding if it must always be removed.
