Designing Compact Consumer Electronics? Meet the Spring Contact Solution Built for Tight Spaces

See how Harwin’s EZi Range helped a high-end hairdryer manufacturer redesign for compactness — without sacrificing reliability.

Public-facing consumer electronics demand sleek, compact designs without compromising on internal reliability. As devices shrink, PCB space becomes increasingly limited — yet the need for multiple stable contact points across internal systems remains. Harwin EZi Spring Contacts are engineered to deliver the right combination of footprint, contact height, and spring force, supplied in tape and reel packaging for seamless automated assembly.

Key Features: 

• Minimal footprint spring contacts for space-constrained PCB layouts
• Optimised contact height and spring force for consistent electrical performance 
• Supplied in tape and reel for compatibility with automated SMT placement 
• Suitable for multiple internal contact points within a single compact device 
• Reliable performance across high-volume consumer electronics applications 

 

Application and Market: 

Applications: 

• Hairdryers and personal care appliances 
• Wearable and handheld consumer devices 
• Smart home electronics and IoT devices 
  
  

Market: 

• High-end consumer electronics manufacturers 
• OEM product designers and engineers 
• Electronics contract manufacturers (EMS/CM) 

 

Engineering Background: 

High-end consumer electronics manufacturers are constantly redesigning existing product lines to meet market demand for more compact, premium devices. This directly reduces available PCB space while internal system requirements — including multiple contact points across different subsystems — remain unchanged. Connectors must maintain reliable electrical contact, support minimal footprint layouts, and be ready for automated assembly to meet production efficiency targets.

Harwin Solution: 

Harwin’s EZi Spring Contacts deliver: 

• Compact footprint that fits within tightened PCB space constraints 
• Precisely optimised contact height for reliable performance within compact housing 
• Calibrated spring force ensuring consistent contact across multiple internal points 
• Tape and reel packaging for seamless integration into automated assembly lines
