Brass is a material used in various electronic and swing accessories due to its excellent properties. Properties include - 

• high conductivity
  
• corrosion resistance
  
• durability
  
• aesthetic appeal.

Here's an overview of its applications in these two categories:

Brass in Electronic Accessories:

• Connectors and Terminals: Brass is used in electrical connectors, pins, and terminals due to its excellent electrical conductivity and resistance to corrosion. Common in automotive, audio, and electronic circuit applications.
  
• Switch Components: Brass parts are used in switches because they maintain conductivity while withstanding mechanical wear. Found in toggle, rocker, and push-button switches.
  
• PCB (Printed Circuit Board) Components: Brass spacers and standoffs provide mechanical support and electrical grounding. Used in mounting PCBs to ensure proper alignment.
  
• Battery Components: Battery terminals, clamps, and contacts often use brass due to its conductivity and ability to handle mechanical stress.
  
• Heat Sinks and Shielding: Brass is employed in heat sinks and electromagnetic shielding due to its thermal and conductive properties.

Brass in Swing Accessories:

• Chains and Hooks: Used for hanging swings due to brass's strength, corrosion resistance, and attractive golden finish. Ideal for outdoor swings as it resists tarnishing.
  
• Decorative Elements: Brass components are used to enhance the aesthetic of swings, such as engraved plates, ornamental caps, and knobs.
  
• Bushings and Bearings: Brass bushings and bearings provide smooth operation of swing joints by reducing friction. They are durable and resistant to wear and tear, especially for heavy-duty or outdoor swings.
• Swing Frame Hardware: Fasteners like bolts, nuts, and washers made of brass are commonly used for assembling swing frames. Offers a combination of strength and resistance to environmental factors.
  
• Adjustable Mechanisms: Brass is sometimes used in adjustable swing systems, providing both functionality and a premium look.
