Product details

Wholesale Pcb Contact Spring Capacitive Touch Button Spring

The Stainless Steel Compression Spring is a precision-engineered component designed for reliable force transmission in compact spaces. Crafted from high-grade stainless steel, it offers corrosion resistance, durability, and consistent performance across diverse applications. Its cylindrical design with a flattened top and mounting protrusion ensures secure integration into PCB contact systems, capacitive touch buttons, and mechanical devices requiring controlled compression.

Technical specifications

FeatureSpecificationBenefit
MaterialStainless Steel (AISI 302/304)Corrosion resistance, high tensile strength
Load TypeCompressionOptimized for force absorption in confined spaces
Coil DesignCylindrical, evenly spaced coilsUniform stress distribution, minimal deflection
Mounting Protrusion2mm straight extensionSimplifies secure assembly in electronics
Corrosion ResistancePassivation treatedWithstands harsh environments (moisture/chemicals)

Customization guide

Adjustable parameters include:

  • Wire Diameter: 0.3–1.2mm (tailor force-deflection ratio)
  • Coil Diameter: 2–8mm (optimize fit for housing constraints)
  • Total Coils: 5–20 (balance compression travel and spring rate)
    Customization Hint: Modify wire diameter and coil count to achieve specific spring rates (N/mm) for PCB contact pressure or touch button responsiveness.

Get inspired

Ideal for compact mechanisms where reliability and longevity are critical. Use in:

  • Electronics: PCB contacts, capacitive touch buttons
  • Mechanical Systems: Door latches, small motors, vibration dampers
  • Industrial: Sensors, gauges, and equipment requiring corrosion-resistant springs

Supplier's note

  1. Key Breakthroughs:

    • Corrosion Resistance: Passivation treatment extends lifespan in humid/chemical environments by 40% vs. standard steel springs.
    • Fatigue Life: Advanced/Pro models use premium wire alloys, achieving 15–30% higher cycle endurance than industry benchmarks.
    • Temperature Tolerance: Pro model’s electroless nickel coating enables stable performance at 120°C, 20°C above competitors.

  2. Version Selection Guide:

    • Base Model: Suitable for general electronics (e.g., standard touch buttons) where cost efficiency is prioritized.
    • Advanced Model: Ideal for industrial sensors or outdoor devices needing enhanced corrosion/temperature resilience.
    • Pro Model: Required for extreme environments (e.g., automotive engines, chemical processing) where durability and high load capacity are critical.

Example: With the Pro Model’s triple-certified chemical resistance (ISO 9023), you can safely integrate springs into acid-resistant machinery. Paired with its 120°C tolerance, this ensures stable operation in high-temperature industrial settings.

Note: Comparative values assume standard industry benchmarks for compression springs of similar dimensions.
