A touch spring is a flexible, small-scale mechanical component often used in electrical devices, machinery, and other industrial applications. It serves as a contact mechanism, enabling connectivity, flexibility, and resilience in various systems. Below is an ultimate guide to touch springs, including their types, functions, applications, and materials.
What is a Touch Spring?
A touch spring is a spring-like device designed to:
- Ensure electrical contact in devices.
- Provide elasticity and pressure for reliable operation.
- Absorb mechanical shock or vibration.
- Support motion control and alignment.
Touch springs are typically made of conductive metals and used in systems requiring repetitive compression or flexion.
Key Features of Touch Springs

- Durable Material: Made of high-strength, fatigue-resistant metals like stainless steel, beryllium copper, or phosphor bronze.
- High Conductivity: Ensures reliable electrical connectivity in circuits.
- Elastic Properties: Maintains consistent pressure and functionality over multiple cycles.
- Corrosion Resistance: Coated with anti-corrosion layers for durability.
Common Types of Touch Springs
1. Compression Touch Springs
- Provide linear force when compressed.
- Commonly used in battery contacts, switches, and connectors.
2. Contact Touch Springs
- Used in electrical contacts where current needs to flow reliably.
- Found in relays, switches, and circuit boards.
3. Wave Springs
- Compact, flat springs with wave-like ridges.
- Used in tight spaces to save axial space and reduce weight.
4. Torsion Springs
- Provide a twisting force.
- Found in devices like rotary connectors or actuators.
5. Cantilever or Leaf Touch Springs
- Flat, flexible strips used in switch mechanisms.
- Provide spring-back motion when deflected.
