Industrial equipment often requires rugged keyboards and human machine interfaces that can withstand continuous use in harsh environments and extreme temperatures. These custom industrial keyboards need to have excellent tactile response, as well as be sealed against water and dust, and be able to withstand a variety of harsh environments.
Its core characteristics include waterproofing, dustproofing, corrosion resistance, stable and reliable performance, alongside being lightweight, compact, and featuring a long service life.
High environmental adaptability: Exhibits excellent resistance to electromagnetic interference, maintaining sensitive response in complex circuit environments. Withstands temperature fluctuations from -30°C to 80°C, coupled with robust chemical corrosion resistance against liquids such as alcohol and engine oil. Achieves an IP6X protection rating, effectively blocking dust ingress.
User-Friendly Operation: Switch surfaces can be customised with raised textures or Braille markings, enabling operators to locate buttons swiftly in low-light conditions or while wearing gloves. Actuation force is typically designed between 300g and 500g, with a key travel of ≥0.3mm, providing clear operational feedback.
Structural advantages: With a thickness of 0.5–2mm, it is lightweight and significantly reduces installation space requirements, meeting the lightweight demands of portable devices. The integrated design minimises component count, resulting in lower mass production costs.
Flat non-tactile type: Long service life but no distinct tactile feedback upon pressing.
Film convex tactile type: Offers good tactile feedback but has a relatively shorter lifespan.
Raised bezel non-tactile type: Aesthetically pleasing with strong three-dimensional appearance but no tactile feedback.
Metal spring leaf type: The spring leaf serves both as the tactile element and the conductive path, representing the most fundamental and commonly used structure.
