What are the conical capacitive touch springs widely used for?

The capacitive touch springs can be applied in various fields such as household appliances, medical equipment, robotics, wearable technology, automated devices, tools, gas, instrumentation, automotive industries, and more. For example, the capacitive touch springs are now very commonly found in household appliances such as induction cookers, microwaves, ovens, refrigerators, air conditioners, coffee machines, and audio systems, and so on.

FAQ for Conical Capacitive Touch Spring

Q1: How do I determine the best conical spring height to ensure stable touch sensitivity?

A: Achieving the right compression is key. Our conical springs support a working height from 3mm to 50mm. By providing your housing dimensions, we can help calculate the optimal height and spring rate to ensure the capacitive touch area makes firm, consistent contact with your interface panel, minimizing signal interference.

Q2: Can the welding feet be modified if our PCB layout has limited space?

A: Yes. We understand that every PCB is unique. Beyond the standard Single-pin and U-shape pin, we can customize the welding foot shape and size to fit your specific soldering pads. This ensures a secure mechanical connection without interfering with other surface-mount components.

Q3: Are these conical springs durable enough for high-frequency use in industrial control panels?

A: Absolutely. We use industrial-grade materials like Stainless Steel, Music Wire, and Phosphor Bronze. These materials, combined with Nickle-plated or Tin-plated surface treatments, provide excellent fatigue resistance and are acid and alkali-resistant, ensuring long-term reliability even in harsh industrial or kitchen environments.

Q4: What is the advantage of using a conical shape over a standard cylindrical touch spring?

A: The conical structure offers a more progressive spring rate and is often more stable under compression. It allows for a larger top capacitive touch area (Φ5-40mm) while maintaining a smaller footprint on the PCB. This makes it a highly efficient solution for modern, sleek capacitive touch panels.

Q5: We are in the prototyping stage; what's the fastest way to test these in our assembly?

A: We offer a rapid prototyping service where free samples can be completed in as little as 1 week for urgent projects (standard is within 3 weeks). Simply share your PDF, DXF, or STEP drawings. If you don't have drawings yet, just provide the outside diameter, working height, and quantity per PCB, and our engineers will handle the design for you.
